Features
- Accuracy of relative humidity measurement: ±2.5% relative humidity from 5 to 95% at 23 °C
- Accuracy of temperature output: ±0.4 °C from -30 to +100 °C
- Accuracy of dew point temperature output: ±0.5 °C from 30 to 95 %RH
Description
Programmable temperature and humidity transmitter is 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.
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 is equipped 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.
