Applications
These rugged pressure transmitters are
designed for use in industrial and
commercial OEM applications.
Hydraulic and pneumatic equipments
Process control and monitoring
Machine tools and automatic
machinery
Air conditioning and refrigeration
Servo valves and drives
Air and gas compressors
Do manufacture customer designed OEM
pressure transducers and
transmitters………
P417 series low cost pressure transducers and transmitters
are perfect for high volume OEM applications for
measuring pressure of gases and liquids in industrial
applications.
The transmitter is engineered for the price and performance
requirements of original equipment manufacturers and is
extremely versatile and suitable for measuring static
pressure. The built-in ceramic measuring cell is highly
corrosion resistant, stable and low temperature drift.
Thanks to their high natural frequency and the rugged
construction the transmitter withstands high shock and
vibration.
The transmitters are available as absolute and relative
pressure types with either 2-wire current or 3-wire voltage
output. 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. The output signal of this bridge is converted
into a standardized current or voltage output signal.
Also, the precision pressure transmitter with ±0.25%
FSO is available on special request.
