These excessive-quality mechanical pressure switches have been developed particularly for security-crucial functions. The nice advantage of mechanical pressure switches is that no provide voltage is required for the switching course of.
In production, the switches are traced by quality assurance software program at every step and subsequently are one hundred % tested.
Due to its compactness, the mannequin PXA strain switch could be put in in measurement environments with restricted area. The sturdy switch enclosure from chrome steel 316 can stand up to the tough and corrosive operating situations of the method trade with working ranges of up to 1,000 bar.
The strain switch is fitted with micro switches, which make it potential to switch an electrical load of as much as AC 250 V, 5 A immediately inside a repeatability of 1 % of the set level.
Depending on the applying, the appropriate variant for the contact model and the electrical connection could be selected; e.g. hermetically sealed micro switches are suitable for corrosive ambient situations and DPDT contact variations for two separate circuits.
A Belleville spring ensures simultaneous triggering of the DPDT contact and increases the steadiness and vibration resistance as a result of snap-performing behaviour.
For safety applications, the stress switch is optionally obtainable with SIL-2 or SIL-3 functionality.
Applications
Pressure monitoring and management of processes
-Safety-important functions in general course of instrumentation, especially within the chemical and petrochemical industries, oil and gas industries, energy generation incl. nuclear energy vegetation, water/wastewater industries, mining
- For gaseous and liquid, aggressive and highly viscous or contaminated media, additionally in aggressive ambience
- For measuring factors with limited house, e.g. management panels
The most essential criteria for choosing the right strain switch are:
- the kind of stress
- the application area (e.g. Ex or security system with SIL necessities)
- the setting range (at which stress the stress switch should switch) and the working vary
- the contact model (what number of switch factors does the customer have, how many circuits does the customer need to manage)
- and the electrical ranking
