Programmable humidity and temperature transmitters with 4-20mA output
* temperature
* relative humidity
* dew point temperature
* absolute humidity
* specific humidity
* mixing ratio
* specific enthalpy
* compressed air measurement
Programmable temperature and humidity transmitters are equipped with temperature and relative humidity sensors. Measured values are also converted to other humidity interpretation - dew point temperature, absolute humidity, specific humidity, mixing ratio or specific enthalpy. Degrees Celsius and Fahrenheit are user selectable. Transmitters are available in wall-mount, duct-mount and bar types. Also types with T+ RH probe on a cable are available. Model T3111P is designed for compressed air measurement up to 20 bars. Transmitter contains a microprocessor based control circuitry in a durable plastic case with connection terminals and sensors in a filter with stainless steel mesh. Humidity transmitters are also available with two galvanic isolated 4-20mA outputs. Configuration of outputs and output range are user adjustable. Large dual line LCD for simultaneous display of T+ RH or other humidity interpretation is an advantage. Display is possible to switch off. Computerized design ensures temperature compensation of the humidity sensor and fail indication. State-of-the-art capacitive polymer sensor ensures excellent calibration long term stability, inertia against water and condensation. Transmitters are designed for use in non-aggressive environment.
APPLICATIONS - measuring and control of air humidity at:
* building HVAC management
