Differential Pressure Switch
Pressure Switch PS600The switches can be used in ventilation, air conditioning and in particular for monitoring air ducts, air filters and fans. The switches are suitable for air and non-aggressive gases. |
|
Application:
Suitable for all practically neutral media such as process water, heating
water, neutral gases, oils. Suitable for two-point control by
means of a continuously adjustable switching point (between 10 and
100 % of pressure range).
Function
A robust diaphragm type movement serves as the basis for this unit. It is
suitable for pressure, vacuum and differential pressure measurements.
The unit uses the same principle of operation for all three measuring
applications. The pressure or the differential pressure applies a force
to one side of the diaphragm. This force displaces the diaphragm
system and moves the measurement range spring. A switching
plunger fixed to the diaphragm actuates an electrical switching element.
The switching point is adjusted via a knurled knob according to
the scale. |

The MLX90210 is a discrete micromachined
Pressure sensor IC suitable for pressure ranges
Between 0 to 1.0 Bar. The pressure medium must be dry and non-corrosive, such as air.
The circuit is a piezoresistive bridge which is realized in silicon through a special micromachining process. As pressure is applied to the bridge, a differential voltage change is seen across the Vout pins, while a bias voltage is applied to the Vexc pins.
The MLX90210 is a versatile pressure sensor solution which can be directly interfaced with other Melexis ICs such as the MLX90308, which provides amplification, signal conditioning as well as the bias current to supply the sensor itself.
