อุปกรณ์วัดความชื้นสัมพัทธ์ (Relative Humidity and Temperature Transmitter)
Relative Humidity and Temperature Transmitter
This solid-state transmitter plugs into its wall-mounted receptacle for on-site, continuous monitoring of relative humidity and temperature in critical or controlled environments.
The HI 8666 has an excellent accuracy of ±2% RH and ±1% °C. Each 4-20 mA analog signal can be sent to remote panel meters, controllers or data acquisition systems. The signals are to be powered by separate external voltage sources.
Equipped with a removable sintered cap, the HI 8666 sensor is well protected for the long run against the ingress of dust or unclean environments.
With the sintered cap removed, the sensor’s response time is faster but it is no longer protected from dust or debris.
With the sintered cap installed, the life of the sensor and the instrument is prolonged and less maintenance is needed. This is ideal in some applications, such as food and industrial applictions where reliability rather than response time is the primary objective.
