Transmitter for measuring temperature and relative humidity.

HTDT2500(-420) has a capacitive thin-film element that provides a signal propotional to the relative humidity.  The transmitter has a high degree of accuracy.  The measuring element responds quickly to changes in humidity.  The transmitter has excellent long-term stabilty and a low hysteresis.  It can withstand up to 100 % RH (condensing) without accuracy being affected.

Filter : The transmitter sensor element is protected by a membrane filter. This can be changed to a sintered brass filter, which is recommended if operating in an environment with a high degree of pollution.
