5437A2 PR Electronics 5437 Temperature Transmitter Various Input, 7.5 → 48 V dc

5437 HART 7 Dual Input Temperature Transmitter_x000D_ PR Electronics 5437 dual input temperature transmitter offers unrivalled performance in the most demanding of applications to convert a wide array of input types to a 4 – 20 mA output signal. The transmitter has 7 input terminals measuring one or two sensors, including two 4-wire RTDs, with individual sensor error detection. Configuring the transmitter with either HART 7 or HART 5 protocols provide flexibility and future proof communication._x000D_ Sensor Inputs_x000D_ The PR 5437 provides unrivalled dual input versatility. Virtually any thermocouple or RTD plus linear resistance up to 100 kΩ, potentiometer, and bipolar mV signals. Input sensor redundancy function maintains process availability and safety by seamlessly switching to backup sensor in the event of primary sensor failure. An alert via HART can be used to allow scheduling of maintenance on the faulty sensor._x000D_ Installation Characteristics_x000D_ Wiring - Innovative housing design means the 5437 temperature transmitter can be wired from either the inside or the outside of the terminals._x000D_ 1/4” centre hole – A large diameter centre hole for easier installation over a wide range of probe mounting diameters._x000D_ Loop test pins - Accessible test pins allow measurement of loop current directly while maintaining loop integrity._x000D_ Status LED - On-board LED indicates faults according to NAMUR NE44 and NE107._x000D_ Jumper pins - Jumpers allow selection of write protection and transmitter burnout options._x000D_ Features and Benefits_x000D_ • LED provides visual notification of sensor, transmitter, and loop status_x000D_ • HART 7 and HART 5 communication protocols_x000D_ • Sensor redundancy function switches to backup sensor in the event of sensor failure_x000D_ • Sensor drift detection maintains measuring point reliability_x000D_ • Flexible dual input capability, with choice of output modes_x000D_ • Superior accuracy ensures true, reliable measurements_x000D_ • Fast response time easily supports safety and cost-critical applications_x000D_ • Very low temperature coefficient ensuring maximum accuracy across changing ambient conditions_x000D_ • High galvanic isolation (2.5 kVAC / 55 VAC) providing protection from ground loops, high voltage transients and common mode interference_x000D_ • Runtime meters provide a valuable history of the process temperature and the ambient temperature around the transmitter_x000D_ 5437A2_x000D_ The 5437A can be mounted in zone 2 and zone 22 / Class I, Division 1, Groups A, B, C, D.
