Contact dial thermometers with gas-filled measuring system are universal instruments for temperature measurement, control and monitoring. DFeatures  enamelled steel case  Protection IP54  different contact arrangements available  standard case height  pointer adjustment from the front  gas-filled, environmentally friendly and safe These switching amplifiers increase the switchingreliability and capability of slow-break and magnetic snapaction contacts, and reduce their contact load.Undesirable switching actions of the limit contactsdue to vibration are greatly reduced by a drop-out delay.Multi-functional relays are strictly recommendedwhen using limit contacts in oil. In the case of inductive limit contacts, transistor relays Type WE 77/Ex.. from Pepperl & Fuchs can be used. The intrinsic safety to EE ia II C T6 is only ensured in conjunction with the transistorrelays mentioned above.
