Combination Sensor — Sensaphone
Sensaphone® introduced a combination temperature, humidity and CO2 sensor that measures and provides real-time values to any Sensaphone monitoring device that accepts a 4 to 20 mA or MODBUS signal. When the sensor registers that a monitored condition falls outside of the programmed range, the system sends an alert with the current value to the operator. It utilizes dual-channel, non-dispersive infrared (NDIR) sensor to monitor CO2, a precision thermistor to monitor temperature, and a thermoset polymer-based capacitance sensor to measure humidity levels. User-friendly features include an LCD display for configuring the sensor and viewing readings. Each combination sensor is encapsulated in a pod that users can easily replace in the field. It is protected from moisture by an IP65-rated enclosure that operators can either mount on a wall or suspend from the ceiling.
