Humidity and Temperature Sensor and Transmitter
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. More details can be found elsewhere in this section.
- 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 diameter 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
Temperature:
- Measuring range: -20°C to +80ºC
- Accuracy: ±0.2ºC, ±0.15% of reading
- Output: 4 to 20mA configurable
- Response: (63% of full value) without filter 6 seconds, with filter 2 minutes
- Power supply required: 16V to 40V DC
- Ambient operating temp: Sensor -20ºC to +80ºC, Electronics 0ºC to +60ºC
- Junction box dimensions: 80 x 84 x 44mm (HxWxD)
