MELA-Humidity/-temperature sensors in these series are used to measure relative humidity or temperature or relative humidity and temperature in air and other non-aggressive gases in explosion hazardous arears and in locations with inflammable dust.
The sensors comprise a sensor part with a sintered filter mounted on a robust aluminium die-cast housing (transmitter part), both made of stainless steel.
Connection to a non-intrinsically safe electric circuit for humidity (F*C3.Ex/8) and for temperature sensors (T*C3.
Ex/8) is achieved with a 1-channel transmitter power supply unit and for the combined humidity and temperature sensors(K*C3.Ex/8) either with a 2-channel or with two 1-channel transmitter power supply units with galvanic isolation between input-/output circuits and power supply.
