time in 15 seconds. Transmitter shall operate over a humidity range of 0…90% RH
and a temperature range of -5° to 55°C (+23° to +131° F). Transmitter to be
powered by 12 to 35 VDC or 12 to 24 VAC, consume not more than 6 mA, and
provide a linear output signal of 0 to 1 V corresponding to 0…100% RH or be
powered by 15 to 35 VDC or 15 to 35 VAC, consume not more than 6 mA, and
provide a linear output signal of 0 to 10 V corresponding to 0 to 100% RH.
Temperature sensor shall be a platinum 1000 RTD with a linear output of 0
to 1 V or 0 to 10 V corresponding to -5° to 55°C (23° to 131°F) with an
accuracy of ±0.3°C ( ±0.54°F) at 25°C.
