Electronic contact Type KE
Electronic contact Type KE for pressure gauges and thermometers
- Electronic contact system for reliable contact function for e.g. PC-system
- Vibration proof
- For dry and liquid filled instruments
- 1 or 2 contact points
- Break, close or shift function
- Working voltage 10-30 VDC
- 100 mA load (transistor outlet)
- Long durability
Application
Contact type KE is well-suited for all applications in processes where vibrations or transients occur as, due to the electronic tracker, these will not cause undesired contact operations. An electronic contact secures a long lifetime in places where often repeated contact operations occur.
The contact system type KE is applicable for all purposes where an electric impulse is wanted at a desired value. The impulse is applicable for alarm functions or simple actuating controls like e.g. a EDP-system, PC-control or a PLC with very low load.
With a few exceptions, TEMPRESS’ pres-sure gauges and thermometers can be delivered with one or two built-in contacts type KE.
The contact is made with a built-in electronic tracker and electronics which secure a reliable and optimal contact function at very low loads, e.g. few mA which is normal in various actuating systems.
Contact type KE does not require an external amplifier relay.
