The Trafag EXPK 944/947/953 ex 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 VH6 level switch is a secure and reliable solution for monitoring fluid levels. The VH6 level switch is installed at the side using G¾ or G½ thread sizes. The time-tested float principle and a potential-free contact as the signalling transmitter guarantee a high level of operational safety. The rising level in the tank forces the float up. Via paddle system, the magnet changes its position relative to Reed contact and actuates it. The repulsion between the two homopolar magnets and supports the buoyancy (Version VK… different). As soon as the level sinks again, the float follows also, and the magnet actuates the Reed contact again. Works adjusted switching function contact makes with a rising level contact opens with a falling level Can be changed by the customer. The Reed contact (3) used as signalling transmitter consists of two ferromagnetic contact-making tongues positioned in a shielding gas-filled glass bulb. As a result, burned contacts are virtually eliminated. This construction enables durability up to 100 000 000 switching cycles.
