These high-quality mechanical pressure switches have been developed especially for safety-critical applications. The great advantage of mechanical pressure switches is that no supply voltage is required for the switching process.
In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested. The robust switch enclosure from stainless steel 316L can withstand the rough and corrosive operating conditions of the process industry with working ranges of up to 600 bar. The pressure switch is fitted with 1 or 2 microswitches, which make it possible to switch an electrical load of up to AC 250 V, 20 A directly.
For lower switching power ratings, such as for PLC appli-cations, argon gas-filled microswitches with gold-plated contacts are available.
■ Pressure monitoring and control of processes
■ Safety-critical applications in general process instrumen-tation, especially in the chemical and petrochemical indus-tries, oil and gas industries, power generation incl. nuclear power plants, water/wastewater industries, mining
■ For gaseous and liquid, aggressive and highly viscous or contaminated media, also in aggressive environments
