Presostatos

Relative pressure The relative pressure measures the pressure relative to the atmospheric pressure. Its working principle is membrane that deforms when receiving pressure acting on the microswitch. Sensotec Instruments has presostatos REGULAUTO manufactured by Bourdon  Sedeme, nowadays BAUMER. The most common models are the RP2N, RP2Y, RP2E, and series RPP. Can have different configurations or options such as: Microswich type. Depending on the sensitivity, cutting capacity, number of contacts (one, two independent or two simultaneous), performance (SPDT, SPST, etc.), hermetic contacts, gold plated, etc. Deviation. Equivalent to hysteresis del presostato and can be fixed or adjustable. Specific devices: Versiones tropicalizadas, [...]

Relative pressure The relative pressure measures the pressure relative to the atmospheric pressure. The electronic presostatos are pressure transmitters that incorporate a visualisation electronics integrated in the device. This electronics allow visualising the pressure and adjust the value where to actuate the contact activating the PNP or NPN when reaching the set value. Unlike mechanical switches, electronic equipment provides better accuracy and sensitivity (resolution). The most common models are the DS200, DS210, DS400 and DS200P. Absolute pressure The absolute pressure measures pressure relative to vacuum. The electronic presostatos are pressure transmitters that incorporate a visualisation electronics integrated in the device. [...]
