The P4/P60 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. 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 WIKA 990.31 diaphragm seal with threaded connection in a plastic version is suitable for versatile application areas in the water supply and wastewater treatment industries. Mounting of the diaphragm seal to the measuring instrument may be made via a direct connection or a flexible capillary. The WIKA 990.31 diaphragm seal is used successfully in chemical plant construction, electroplating and wastewater treatment applications.

The SIKA D-Ex digital pressure gauge is suitable for both stationary and mobile measurement and display of pressure. The SIKA D-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. Tare / Zero-Function User-defined zero point setting at the push of a button makes offset adjustment easy and eliminates the need for tedious mechanical adjustment. Single-point adjustment allows the linear characteristic curve to be shifted in positive or negative direction over the entire measuring range. Selectable pressure units Another feature is the large selection of pressure units. Up to 6 different units are possible “ far more than any complicated dual-scale or multi-scale gauge can offer. The required display unit is selected directly on the digital pressure gauge and is indicated on display. No conversion necessary; the desired value can be read directly. Min / Max Displays and Peak function Experience shows that excess pressure and pressure peaks significantly higher than normal operating pressure occur at some measuring points. Min / max displays and fast peak value measurement cycles in digital pressure gauges assist in system analysis and allow peak values to be determined. This allows incorrect readings and violations of range limits to be detected and helps avoid damage to pressure systems. Preventive service is often less expensive than repairing or replacing defective instruments.

The Danfoss CS pressure switch series has a built-in pressure operated, three-pole switch. The contact position of which depends on the pressure in the connector and the range setting and adjustable differential. The Danfoss CS pressure switches are fitted with a manual switch that will lock the contact system in the open position independently of the pressure in the system. Pressure switches with relief valve are used in compressed air systems where pressure relief on the compressor piston before the start is required. The CS is suited for an automatic start and stop of air compressors and water boosters.
