Static / Dynamic Measurement Pressure Sensor
Static / Dynamic Measurement Pressure Sensor

The key to measuring highly dynamic pressure variance is to achieve, as far as possible, a direct connection between sensor element and medium. With this in mind, KELLER has come up with a micromechanical solution without media isolation diaphragm (with its damping effect), capillary tubing, sealants or adhesives. In the M5 series, the rear of the silicon sensor is soldered to a supporting element designed for fluid dynamics, which in turn is secured flush at the front of the pressure connection. This design enables dynamic measurements with a bandwidth of 0...50 kHz and offers a number of additional benefits. These include high decoupling of mounting forces and structure-borne vibration, extensive media compatibility and the durability offered by the anti-oxidation coatings. Other features are the overpressure protection of up to five times the measurement range and pressure connection with an external thread of Ø 5 mm for installations in space-limited locations.

The pressure sensors in the M5 series are intended for operating temperatures between -40°C and +180°C with a narrow total error band (i.e. including temperature errors) of ±1%. Without the remote signal converter, they come with a typical output signal range of 80 mV (based on a 1 mA supply) and an individual calibration certificate. The 3 bar, 10 bar and 30 bar measurement ranges are available for absolute pressure measurements. Separating the pressure sensor and the signal converter enables measurements at close proximity, even in units installed in cramped conditions and exposed to high temperatures.
