P300 series compact designed pressure transmitter
meets the requirements for a general purpose, reliable
ａnd economical pressure measurements for industrial
ａnd process control installations. This pressure
transmitter measures of gases and liquids in industrial
applications and is available wide range of pressure in
0.1 to 500kgf/cm2 relative or absolute pressure. It is
extremely versatile and suitable for measuring dynamic
ａnd static pressure.
The built-in piezoresistive silicon or ceramic measuring
cell is highly corrosion resistant, stable and an excellent
price / performance ratio. The transmitters are available
with either 2-wire current or 3-wire voltage output. The
measuring principle of ceramic sensor is that the
pressure to be measured acts without transmitting liquid
on a stable, corrosion resistant ceramic measuring cell.
Piezoresistive resistors are attached to the cell and
connected into a Wheatstone bridge configuration. In
case of isolated silicon sensor, the pressure to be
measured acts through thin corrosion resistant stainless
steel 316L diaphragm on a silicon measuring element.
The pressure transmitting medium is silicon oil. The
measuring element contains diffused piezoresistive
resistors which are connected into a Wheatstone bridge.
The output signal of this bridge is converted into a
standardized current or voltage output signal.
