You never have to worry again about losing critical temperature measurements because of a sensor failure thanks to the new THZ3 and TDZ3 Smart HART® Dual Input Temperature Transmitters from Moore Industries. With two inputs, users can select one as a backup in case there is a failure with the primary sensor. If there is a problem with the main sensor, the transmitter automatically switches to the backup sensor.
Failure protection is just one key feature of the new dual input THZ3 and TDZ3. Other features include:
- Average and differential measurement: Average the readings from two sensors in tanks where stratification can occur. Use the differential measurement capability to monitor the temperature delta across a heat exchanger for efficiency or BTU calculations.
- High-Select and Low-Select: Use two sensors and select the higher or lower one as a basis for control. High-Select and Low-Select enables you to reduce the chance of an over-temperature or under-temperature situation.
The THZ3 and TDZ3 also come with Device Intelligence, a series of features for smarter control and monitoring including:
- Sensor drift and corrosion detection that checks and alerts users when the sensor is drifting out of a preset range or when the resistance due to corrosion exceeds set parameters.
- Smart range alarms with four HART alarms – set to any input or calculated input – that detect when the variable is within or outside of user preset limits.
- A High Availability option that enables the selection of how the AO behaves when there is an input failure or out-of-range value detected by the transmitter. By utilizing the input simulation feature, users can manually input a digital input signal that allows the testing of the AO and any HART or diagnostic alarm.
