SPI19S Pressure sensor

Product catalog summary

Product Introduction
The SPI19S pressure sensor features a high stability piezoresistive sensor die encapsulated in a SS316L base. It uses a stainless steel diaphragm and sealed silicon oil to isolate the sensor die from the measuring medium, making it suitable for various liquid mediums.

Features

High stability piezoresistive sensor die
Current excitation
Isolated structure for various fluids
316L stainless steel construction
Available in Hastelloy C and Tantalum
φ19mm standard/OEM sensing element

Applications
The sensor is used in industrial process control, gas and liquid pressure and level measuring, pressure measuring instruments, pressure calibration instruments, hydraulic systems, refrigeration equipment, and air conditioning systems.
