PT70 Series of Smart Differential Pressure Transmitters with smart LCD, HART and 100:1 turn-down ratio are two-wire microprocessor based instruments, which can recieve two pressure lines and indicate the value of the differential pressure from these lines on its wide LCD display and generate a 4-20mA output signal directly or inversely proportional to the pressure differential of the input lines. Digital communication for remote calibration and monitoring is also provided, superimposing a digital signal on the same pair of wires that carries the 4-20mA signal.


PT70 utilizes the proven piezoresistive silicon technology. Deflections of the diaphragms under pressure are transferred by a manometric fluid to the sensor to produce very highly accurate measurement. Thermal drift is automatically compensated using the signal from a thermistor integrated into the pressure sensor.


The high accuracy sensor coupled with the temperature compensation feature gives a measurement precision, which is more than adequate for even the most demanding applications. Due to the materials and technology used in construction of these pressure transmitters, these instruments are excellent in reliability, showing resistance to corrosion against the many chemically aggressive media, functioning well in tropical environment and withstanding mechanical shocks.
