| The Preso ThermoTrack is a non-invasive ultrasonic flow meter combined with non-invasive temperature sensors manufacturers, to measure energy use in water-based HVAC systems. No sensors come in contact with the liquid and there are no moving parts, so downtime and maintenance are eliminated. The flow meter utilizes transit time ultrasonic technology and the temperature sensors are Pt1000 RTDs. The flow rate, supply line temperature and return line temperature measurements provide the necessary inputs to calculate energy use, displayed in BTUs, Calories or Watts. The ThermoTrack is available for pipe sizes 1/2" (12 mm) and larger, with a variety of power source and output options available. |

These automatic speed controllers are fully digital and control the rotational speed of single phase (230Vac/50Hz) voltage controllable motors according to temperature.
TEDS controllers can be used in ventilation and in heating applications and provide a great number of user adjustable options. All data is visualized on a liquid-crystal display (LCD), presented by user friendly and intuitive multilanguage menus. The parameters can be set through 4-button keypad (supplied with a lock function). There are user-installer priorities set by passwords. The temperature range is from 5 to 35 °C (standard).
TEDS controllers provide auto and manual operation modes, possibility for calibration and input adjusting, additional professional remote control input (heat/cool - day/night switching), kickstart with programmable time duration, min and max speed limitations, off level with adjustable hysteresis, digital
readout, TK protection, internal real-time clock with two level switching (day/night), outputs for cock (230 V)and slave/power units (0-10 V). Temperature sensor suppliers TES-55-150R is included.
The proportional range can vary between 2 and 30 °C. When the current range is insufficient (connection of several motors), the power module ERV10 can be used as a slave controller. |

Minco humidity and humidity plus manufacturer of temperature transmitters are designed using an advanced microprocessor. Digital signal processing allows these professional transmitters to precisely match the characteristics of the moisture sensor to a wide range of RH and temperature values found in the many applications the product serves.
The humidity sensor is comprised of an integrated circuit (IC) with a stable polymer element and platinum RTD that is used for temperature compensation. This sensor offers outstanding resistance to airborne contaminant and chemicals, and is protected by a sintered stainless steel professional filter which resists condensation.
Wall/Duct/OSA mounting configurations
Accuracies of ±1% or ±2% RH
Temperature compensated
Temperature output option
Two-point field calibration
NIST traceable calibrations

HumiTracTM features a NIST traceable, field-replaceable sensor tip module that allows the end user to replace the sensor on-site and maintain ±2% RH accuracy and NIST traceability. This virtually eliminates the need for time consuming and costly factory calibration, while reducing downtime during service intervals to near zero. HumiTracTM is designed to be highly configurable in the field - by minimizing the necessary number of orderable configurations, GE reduces distributor inventory costs and provides maximum flexibility to the installer. All versions feature field-selectable outputs (0-5V, 0-10V, 4-20mA) and passive temperature versions incorporate both a 3K and 10K O thermistors. Signal-conditioned temperature versions are available scaled from 0 to 50°C or -40 to 60°C. HumiTrac is available in humidity accuracies of ±2% or ±5%, and offered in wall mount, professional duct mount and outdoor air configurations.

Professional press Man is a simple but yet efficient controller for maintaing constant pressure in heating and ventilation environments. It is charactized by a very robust construction and extremely simple user interface.
Press Man controls the PROFESSIONAL HVAC pressure from an pressure transmitter with an analog output mounted directly in the ventilation system. Difference pressures can be obtained by incorporating mecanical blends etc. IP54 grade and integrated keys / display makes Press Man well suited for many applications.
Press Man has a setpoint, which is controlled by the arrows. A single press will put the setpoint one up or down, holding the arrows will make the setting change fast while pressed. Measured pressure will be displayed pr. 5 sec after keys have been released
Press Man has two relay outputs, the first is used on ON/OFF by the key setting, the other is used for alarming. ON/OFF is activated as the key is activated, the alarm output will be active when the output can not be reached whithin 30 minutes !. Means, that if the output internally is UNDER or OVER the MIN/MAX settings, the relay will activate. Flashing LO or HIGH in display
Press Man can indicate the real output for the attached speed controller, OR, it can indicate the real input from the attached pressure professional transmitter. Both values will indicate in percentage (0-100) of input and output)
Press man can be 100% stopped, pressing the ON/OFF button. Display will indicate OFF and the DC output will be forced to 0, as will be the 2 relays. Press man has individual settings for minimum and maximum speed for the attached speed controller. Settings to be controlled by MIN/MAX buttons. Parameters for Proportional Band and Integration Time is done from the keypads as any other parameter. The PI regulator will meassure the pressure, compare it to the setpoint and try to maintain the dc output to make the real pressure as close to the setpoint as possible. |
