Transmitters of the EE21 series have been developed for high-precision measurement of relative humidity and temperature. EE21 transmitters are available for wall and duct mounting with or without the very useful
snap in-mounting kit, which allows a quick and easy exchange of the transmitter.
Outputs can be selected between voltage and current. An optional radiation shield providing a forced ventilation is recommended for use in outdoor applications.
Special protection coating for the sensing element permits the permanent use in very pollutedenvironments.
Measuring range: 0...100% RH; -20...60 °C
Outputs: 0...1/5/10V or 4...20mA
Accuracy: +/-2% RH; +/-0.3 °C
Supply: 24V AC/DC

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, duct mount and outdoor air configurations.

It exists two kinds of thermistors : NTC and PTC
(see these headings for technical information)
For the temperature probes it's generally a NTC
thermistor which is used. In such case American
are preferred for their accuracy and long term stability
These sensors are frequently welded at the end of leads
or cables, with or without a shield, depending of use.

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….
