Temperature and Humidity Transmitters

Product Details:

Libratherm offers a low cost, rugged and reliable Duct Mount Humidity Sensor cum Transmitter HX-440-DM for sensing T or RH or T + Rh in the environment and transmitting the proportional analog values (4-20) mA or (0-10) VDC.
Normally, the signal generated by T+RH sensors is low in strength hence cannot be transmitted over a very long distance, and if done so the signal is likely to drop over a very long cable which will result in the inaccurate measurement of temperature and %RH.
The Resistance Humidity Detector featured here converts these low-level signals from Pt-100 and Rh sensor to equivalent 4-20mA/0-10Vdc linear analog signal, which can be transmitted over a very long distance without loss of accuracy in the measurement. Dual 4-20mA proportional to T and %RH can be used for remote measurement and indication and control.
This Hygrothermo Transmitter operates on a 24VDC power supply and is housed in an ABS plastic enclosure with perforation for sensing. The 24VDC supply and 4-20mA are electrically isolated from each other and hence prevent any ground line interferences or loading effect, while connecting to any external measuring/controlling devices like DCS, PLC, BMS controller, HMI, DDC, or PID controllers. Standard 4 core or 6 core 2-meter cable with end terminal is attached to the transmitter for ease of connection and wiring.
Key Feature:

• Accurate Capacitive sensor for RH
• Accurate Pt-100 sensor for temperature
• Operates on 24VDC
• Imported Honeywell sensor
• Duct type and Wall mount models
• 4-20mA output for Temperature and RH
• 4-20mA output and power supply ground is electrically isolated
• ABS plastic / SS enclosure for industrial use
• Standard 2 meter cable

Applications:

• HVAC / AHU / Humidifiers /Foggers and De-humidifiers
• Pharma Labs / Manufacturing Plants
• Data Center / Server rooms, Green Houses, Ware Houses, etc
• Textile Industries

Product Details:

Pt100 sensors are the most common type of platinum resistance thermometer. Often resistance thermometers are generally called Pt100 sensors, even though in reality they may not be the Pt100 type. Pt refers to that the sensor is made from Platinum (Pt). 100 refers to that at 0°C sensor has a resistance of 100 ohms (Ω).

A resistance thermometer is a type of temperature sensor. It consists of an element that uses resistance to measure temperature. 

Pt100 sensors can be protected in several ways and the temperature sensors designed to get the best measurement of your process.
