BESKRIVNING

The BASI BRHT200 transmitter measures relative humidity of air and non-aggressive gases and convert it into standard 4...20mA two-wire current signal. This transmitter use thin film or solid state sensors, which capacitance changes proportionally to environmental relative humidity value. All BRHT200 transmitters have a built-in temperature drift compensation system, which guarantees good stability of measurement. An additional platinum temperature sensor or second two-wire transmitter may be built-in for measurement of both medium relative humidity and temperature. BRHT200 transmitters are available in three modifications with

different cases, mounting, and temperature ranges. The specific design of the electronic block allows the user to adjust the output on-site. All this, in addition to the high environment protection class, the small size, and the low price, make BRHT200 transmitters convenient solution for many relative humidity measurement applications.
