Temperature and Humidity Transmitters
Temperature and Humidity Transmitters
This relative humidity and temperature transmitter complete with sensors continuously measures temperature and humidity and provides a 4-20mA output signal over the range of both sensors. The transmitter is housed in a sturdy Macrolon box rated to IP67. There are three styles of mounting. Wall mounted, duct mounted (using a compression fitting) or wall mounted with remote sensor. A dust filter is available as an option. A dual display indicator/on-off indicator/controller reference 715-115 is available to suit this humidity/temperature transmitter.
- Probe dimensions:
Wall mounted, 135mm long x 14mm diameter
Duct mounted, 135mm long x 14mm diameter (mounting flange and gland required)
Remote mounted, via 2 mtr leads to 135mm or 335mm long x 14mm dia. probe
Relative Humidity:
- Measuring range: 5% to 98%
- Accuracy: ±2% RH - 5 to 90% RH; ±2.5% RH - 90 to 98% RH
- Output: 4mA = 0% RH, 20mA = 100% RH
- Response: (63% of full value) without filter 6 seconds, with filter 3 minutes
- Accuracy: ±2% RH - 5 to 90% RH; ±2.5% RH - 90 to 98% RH
