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.

Minco models AH71, AH72, and AH73 are 2-wire temperature compensated humidity transmitters that are FM and CFM approved for use in hazardous locations. Intrinsically safe models are available with an optional temperature transmitter output. The AH73 is also available with an optional digital display for remote indication of relative humidity and temperature.
The transmitters utilize a thin film capacitive humidity sensor which provides outstanding sensitivity and chemical robustness. The transmitter converts the humidity sensor’s signal into a 4 to 20 mA DC current, which changes proportionally from 4 mA at 0% RH to 20 mA at 100% RH. The optional temperature loop produces a second 4 to 20 mA DC output where the current changes from 4 mA at the lowest temperature of the range, to 20 mA at the top of the temperature range. The leads that supply power also carry the current signal.
- Accuracy of ±2.5% RH
- Temperature compensated
- Temperature output option
- One-point field calibration
- NIST traceable calibrations

The HMP228 is a fast, reliable and accurate on-line detection system for water in oil.
Moisture measurements from lubrication oil can significantly cut maintenance costs and prolong machine lifetime. The HMP228 measures water activity and temperature from oil. In connection with oil, water activity measurement offers several advantages compared to the traditionally measured variable, parts per million (ppm). Water activity indicates directly whether there is risk for free water formation. The measurement is independent of the type, aging or temperature of the oil.

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 Pt-100 class A element for temperature sensing and Monolithic sensor for %RH sensing. 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. Using 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. 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….
