iSOLV SPT200

SPT200 Series Smart Pressure Transmitter are microprocessor based with HART® (Highway Addressable Remote Transducer) protocol communication. Automatic temperature compensation significantly improve stability in pressure measurement.

SPT200 Series Smart Pressure Transmitter are widely use in petrol chemical, chemical, oil & gas, steel, power plant, water & waste water, manufacturing and other industries. With the unique sensor technology, combined with diaphragm material available in various options, the industrial transmitters are suitable for almost all industrial gases and liquids.

SPT200 -D

The differential pressure transmitter includes two functional units:
— Main unit
— Auxiliary Unit

The main unit includes a sensor and process connection. The completely welded sensor module is a twin-chamber system with an integral overload diaphragm, an absolute pressure sensor, a temperature sensor and the silicon differential pressure sensor. The absolute pressure sensor, which is only exposed to the pressure at the high pressure side, acts as a reference value to compensate for the static pressure. The temperature sensor as a temperature compensated reference value to compensate for the temperature drift.

SPT200 -G

The gauge pressure transmitter includes two functional units:

— Main unit
— Auxiliary Unit

The main unit includes gauge/temperature sensors and process connection. The low pressure span completely welded sensor module is a twin-chamber system with an integral overload diaphragm, and a silicon pressure sensor. The temperature sensor as a temperature compensated reference value to compensate for the temperature drift.
