New! The Vaisala Combined Pressure, Humidity and Temperature Transmitter PTU300
Vaisala introduces a new generation barometric pressure, relative humidity and temperature transmitter series, the Vaisala Combined Pressure, Humidity and Temperature Transmitter PTU300. The PTU300 features fully digital measuring electronics for all three parameters, several small RH&T sensor heads for different applications, and calculated humidity variables. The new backlit display shows three-hour graphical trends and up to one year of historical data. The recorded measurement data can be viewed on the display or transferred to a PC. Seven languages options are also available.
The PTU has four different probe options: PTU301 for laboratories, PTU303 for outdoor use, the warmed PTU307 probe for demanding meteorology, and the PTU30T for pressure and temperature measurement only.
The Vaisala BAROCAP® sensor is used for pressure measurement and the Vaisala HUMICAP® sensor measures humidity. Both sensors are known for their high accuracy and long-term stability. The temperature sensor is a platinum RTD sensor.
Applications include environmental monitoring in calibration laboratories, GPS meteorology and weather stations.

Temperature Transducer 0-10V / 4...20mA
The MU/E transducer measures the temperature by the Pt100-Sensor-Input and transforms it to a standardised analogue output signal 0-10V or 4...20mA.
=> DIP-Switching Panel
You can choose between 16 measurement ranges by DIP-Switch, e.g. -50...+50°C, -30...+70°C, -20...+150°C, 0...+50°C, 0...+200°C etc.
An easy temperature adjustment at -1K, -2K, -3K is also possible.

ComfortSense
Thermal comfort measurement according to EN 13182, ISO 7736 and ASHRAE standard 113
Dantec Dynamics’ ComfortSense system is designed for research and development of heating and air conditioning systems requiring multi-point measurements of air velocity and temperature. Draught measurements require omnidirectional sensors with a frequency response of at least 2 Hz, which is fulfilled by the present system.
ComfortSense elements
The ComfortSense system consists of a main frame with anemometer circuits for up to 16 probes. The omnidirectional probes measure both air velocity and temperature. Six frames can be connected so that up to 96 probes can be monitored simultaneously. The ComfortSense main frame has a built-in A/D converter with USB 2.0 interface.
Easy-to-use
It is easy for the user to setup a measurement sequence and make a measurement grid with selection of probes from a user library. The software delivers statistical results based on user-defined measurement cycles. The ruggedly designed probes and cables are perfectly suited for large test rooms.

Product Description:
Libratherm offers micro-controller based Process Transmitter model PTX-3000 for measuring and transmitting the analogue and digital values proportional to the Process Input. It can accept the universal input, which is user selectable using internal DIP switch. Three options are available, where user can specify the model for universal input, any of the two fixed input or any of the single fixed input. The current output of 4-20mA proportional and linearized to the process input is available for remote measurement and indication. For dual input model, two independent 4-20mA are available. To suit industrial requirement the transmitters are available with and without display.
For serial interface with PLC or DCS or with any other process controller – digital serial communication on RS485 bus with MODBUS RTU protocol in slave mode is also provided. RS 485 interface is advantageous, since number of wires coming from the various sensors can be avoided and instead only two wires can be used to interface on serial port. For example, for a large heating system incorporating 16 thermocouples, under conventional method 16 dual core cables will run from the system to the control panel, where as in case of RS485 interface, only two wires will run from the system to the control panel.

The HygroFlex series is ideal for all applications where exact measurement of humidity and temperature is of decisive importance, e.g. the food and pharmaceutical industries, printing and paper industries, meteorology, agricultural sector, archaeology, climatology, etc. There is hardly a field today in which these parameters may be ignored. It is ultimately the measuring task on hand that defines the instrument that best covers your needs.
The HygroFlex5 series offers you ultimate performance and flexibility thanks to its interchangeable HygroClip2 probes. The transmitters come in wall and duct mount versions. Many useful functions can be accessed with optional HW4 software.
HF5-Series is available with analog and digital outputs, so compatibilty with almost any monitoring or control system is assured. Digital versions may be networked togther to form a dedicated environmental monitoring system using HW4 software.
The new generation device not only has a unique calibration and adjustment process, but also allows probes to be interchanged in just a few seconds. This easy interchangeability during operation reduces down-time and service costs to a huge extent. The possibility of using every probe as a simulator with fixed output values is a big advantage for system validation. In the case of networked devices this can even be carried out online from a remote PC workstation.
Applications
High specification HVAC applications, building management systems, museums, libraries, environmental monitoring systems.

The Ascon’s “H” series includes three humidity transmitters designed to meet the requirements of the HVAC and storerooms applications from the simple ones to the more sophisticated ones.
All transmitters feature a highly accurate capacitive sensor integrated in a silicon microchip. This new technology allows for accurate process measurements, is extremely reliable and offers excellent long-term stability. The sensor is very durable and moisture resistant. For easy and fast replacement the sensor is built into the “Humi-Chip” module, no re-calibration is required. Three types of interchangeable and replaceable filters can be selected depending upon the application, for clean or dusty or aggressive chemicals environments. H1, the simpler model, includes one humidity output and one temperature output. On the other models three outputs are available and configurable for relative humidity, dew point, temperature, temperature and dew point temperature difference. Available output signals are 0/4...20mA 2 wire, 0…1V, 0…5V or 0...10V.
The H3 and H5 models include: configurable alarms with relay output, real time clock and RS485 Modbus RTU for serial communications and configuration. Gateways for Ethernet, PROFIBUS, DeviceNet and CANopen connections are available.
The “H5” model includes alarm events memorization and data logging of the main measurements. For further operator ease of use, on all the models, the relative humidity values can be displayed on the optional integrated LCD display. Housings are IP66 for wall or duct mounting; remote sensor model is also available.

Product Description:
Libratherm offers Relative Humidity and Temperature transmitter model HTX-3000 for measuring and transmitting the analogue and digital values proportional to these two parameters. HTX-3000 is designed using the latest micro-controller, incorporating Rotronic make Hygrclip CP sensor for measurement of Temperature and %Rh . The two independent loop current outputs of 4-20mA proportional to both the parameters are available for remote measurement and indication. To suit industrial requirement the transmitter is available in both duct type and wall mounting type
assembly, and for the local indication of %RH and Temperature, two independent 4 digit 7 segment red LED displays are provided. For serial interface with PLC or DCS or with any other process controller – digital serial communication on RS485 bus with MODBUS RTU protocol in slave mode is also provided. RS 485 interface is advantageous, since number of wires as with the three wire of 4-20mA per transmitter can be avoided (3 wires multiply by no. of transmitters), since only two wires can be looped with multiple transmitters in multi-drop wiring. Optionally, Ethernet output can also be made available. These transmitters finds application in HVAC, Climatic control, Stability chamber, Hospitals, Green houses, useful for Validation agencies and for regulatory requirement of FDA, CGMP, ISO14644 etc….
