P1500 Low Pressure Sensor

High performance low level pressure sensor

About the P1500 Strain Gauge Pressure Sensor

P1500 Series Strain Gauge Pressure Transducers are high grade sensors that provide highly precise measurement of absolute or vented gauge pressures over wide temperature ranges.
Standard versions of this transducer use a 17-4 pH stainless steel diaphragm to sense pressure. The deflection of the diaphragm is transferred to a double cantilever beam by a force transfer rod. Strain in the beam, and therefore, input pressure is measured by four foil strain gauges.
An all-welded construction provides high reliablility and stability. Capable of sensing extremely small changes of applied pressure, the transducers are relatively insensitive to vibration, altitude and shock.
The P1500 Series are available in a range of electrical inputs and outputs. Zero and span potentiometers are availbable as a special option with the P1540, P1550, P1560 and P1590 models.
