Delta Mobrey D72 Series Smart Temperature Transmitter

Delta Mobrey D72 Series Smart Temperature Transmitter

The Delta Mobrey D72 Temperature Transmitters are capable of converting resistance of temperature or voltage of thermocouple sensor to standard current signal 4-20mA. The transmitter has two separate channels enabling measurement of temperature difference, average, average with redundancy, and max. or min. temperature.

Temperature Transmitter has compensation of ambient temperature influences and compensation of thermocouple cold junction using internal/external (Pt100) sensor or constant temperature.

Most of parameters such as: sensor type, measuring range, current alarm signal when electric circuit is broken, output characteristic correction, user characteristic (60 points) are programmed using PC with Hart/USB/Bluetooth converter and Delta Mobrey’s D-Soft configuration software or DKAP-03 communicator. On request Delta Mobrey can set temperature transmitter parameters such as measuring range, type of sensor.

D72 transmitters are designed for field use with standard aluminum or stainless steel case. They can be used with temperature sensors mounted directly on transmitter’s casing or with sensors remotely connected with cable. The model D72 Smart Temperature Transmitter is suitable for measuring temperatures between -200°C and 1820°C, and comes with custom probe lengths and various thermowell options.
