The Trafag EXPD 920/924/932 ex differential pressostat electromechanical pressure switches provide high vibration resistance and switch point precision in combination with an extremely robust and durable design. This results in switches that can be operated for decades without requiring maintenance, even under harsh conditions. Various designs with bellows, membrane and piston sensors cover a wide variety of pressure ranges, media and load profiles for many different applications.

The SIKA P 40.2 pneumatic hand test pump is designed to enable the direct connection of all pressure systems to be tested using adapters. The test sample is easily connected using the rugged industrial hose with integrated quick coupling and supplied adapters. The reference is fitted directly at the top of the pump using a positioning adapter. The required test pressure is initially generated using the handles and then adjusted precisely with the fine adjustment valve. As a result, the pressure on both instruments is the same. The pressure relief valve allows continuous pressure reduction and ensures accurate and easy testing, even with decreasing pressure. Air is used as pressure media. Especially in application areas in which wetting of the test sample is not allowed, or the use of aggressive or ionising substances must be avoided, air is the ideal test medium. SIKA˜s pneumatic test pump type P40.2 fulfils requirements that in many cases can only be covered by several pumps from other suppliers. In the simplest case, the pressure is indicated by an analogue pressure gauge. An easy to read digital pressure gauge or hand-held instrument can also be used. The accuracy or adjustment of the pressure measuring device being tested can be checked by comparing the indicated reference value with the measured value for the device under test. OEM version and full version Depending on the model a matching pressure hose is part of the basic configuration of the OEM version of the test pump. The hydraulic hoses are fitted with a self-sealing quick coupling. Inch, conical or metric adapters for all commonly used connection threads are available in the full version. A matching seal kit is also included with the pump. All of the equipment is held in a carrying case with a foam-rubber insert.

The SIKA L-Ex digital pressure gauge is suitable for both stationary and mobile measurement and display of pressure. The SIKA L-Ex digital pressure gauge can be used as a reference to explain the checking, adjustment and calibration of other pressure measurement devices directly on-site. High accuracy in the signal acquisition is achieved by using high-performance measuring cells with electronic linearisation of the characteristic curve. Suitable instruments are available for a wide variety of measurement tasks. Ease of use is assured by innovative design and advanced technology. All essential functions for everyday use can be selected conveniently at the press of a button. Excellent protection against dust and moisture is provided by a membrane keypad or rubber buttons. Integrated supplementary functions make our digital pressure gauges true all-rounders. PC connection and software Many digital pressure gauges have a serial interface port to allow measurement values and stored data to be transferred directly to a PC and documented. An inexpensive measurement data acquisition system can easily be assembled with suitable software and an interface converter. Processes can be readily monitored and analysed using the recorded and visualised measurements, and all data can be exported using standard programs such as Microsoft Excel. A remote control is also possible. Various software packages with extensive recording and display functions, logger and alarm evaluation as well as for calibration are available. Analogue output An electrical output signal enables remote display on a control console or in a control room as well as the connection of external recorders and indicating instruments. Relay output Digital pressure gauges allow limit contacts to be closed even at low pressures. There is no need for high actuation forces for magnetic spring or inductive contacts, which makes it easier to signal critical equipment conditions and perform supplementary control tasks.

The Danfoss MBC5000 pressure switch and Danfoss MBC5100 pressure switch are used in marine applications where space and reliability are essential features. According to their block design, the Danfoss MBC 5000 and MBC 5100 are compact pressure switches designed to survive in the harsh conditions known from machine rooms onboard ships. The Danfoss MBC pressure switches have a high vibration resistance and feature all commonly marine approvals. The fixed but low differential guarantees accurate monitoring of critical pressures. In addition, MBV test valves can be delivered as a standard option for MBC pressure switches.
