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.
