Siemens 186 Room and Duct Humidity Transmitters


The 186 Room and Duct Transmitters are one-pipe, direct acting pneumatic instruments that sense space humidity and transmit a 3 to 15 psi (21 to 103 kPa) pneumatic signal to a remote receiver gauge and/or receivercontroller to read percent relative humidity.
• Inorganic sensing element for rapid response to humidity changes
• Bimetal temperature compensation minimizes temperature effects
• Cover included with Room Transmitter
• Available for room mounting (vertical) and duct mounting that is at least 6-inches (152 mm) high and 6-1/2-inches (165 mm) deep
