Fischer MS10 is rugged, industrial performance grade pressure switch with onboard dial indicator. It is suitable for monitoring overpressure and vacuum pressure of liquids and gaseous media.

MS10 combines high sensitivity, vibration resistant, corrosion-resistant metal diaphragm with 2 x change over micro-switch. This enable to employ the pressure instrument in variety of industrial and commercial applications.

Working Principle:

The measuring system of MS10 consists of two encapsulated and hydraulically coupled metal diaphragm. When the instrument is subjected to pressure, it causes a deflection proportional to the strength of pressure. Opposite side of the medium-touching diaphragm, a tappet returns the deflection to a motion work and the operating elements of the micro-switches.

When excessive pressure is applied, each metal diaphragm touch and limit itself to chassis of the capsule. This protect the transmitter from overpressure.

Key Features:

• 2 x change-over microswitches

Differential pressure switch from Beck Sensor, Germany for differential pressure, over pressure and vacuum pressure monitoring of air, clean gases, dry vapour for HVAC applications in building, commercial and industrial area. With its adjustable knob, you can set any switching point within the range.

Key Features & Applications:

Most important feature of Beck 930.8x, is its adjustable switching knob, thus user can set switching contacts at any required differential pressure. This peculiar feature makes pressure switch highly versatile, and thus can be used in many control topology in HVAC and air applications.

Another key feature, is high performance contacts, with high switching repeatability, thus making it very very low failure product. This make it highly reliable.

One of the most widely application, is air filter or HEPA filter monitoring in air ventilation. With adjustable knob, user can adjustable level of allowable congestion / clogging in filters due to dust and hence alarm filter status or requirement of charging.

DPS 930.8x is far better than its peer products in every terms whether reliability, easy to work, mounting, repeatability, performance and integration.

Silent Features:

• Adjustable knob to set switch at any desired switching pressure
• Transparent enclosure for ease to monitor switch point
• Squeezing cable gland to dust and moisture protection
• Robust performance over the life
• Easy installation
• IP54 protected
