Specifications
Overview
The Endura pH / Redox (ORP) Sensor TBX587 is the latest addition to our comprehensive industrial pH sensor product line. This new pH sensor uses the familiar solid state Next Step Reference design offered in our TB5 and TBX5 product lines.
The sensor targets smaller 1 in. process connections found in sample lines in refineries, chemical plants, and other industrial applications. This product, combined with the successful TB(X)557 retractable sensor, TB(X)564 high pressure sensor, and the TB18 Safe-T-Clean valve allows ABB to address nearly any insertion sensor installation.Contact design
The model TFS35 bimetal temperature switch can be delivered in two contact designs.
A Normally Closed (NC = closed in the normal state) opens a circuit and shuts down the machinery.
A Normally Open (NO = open in the normal state) closes a circuit on reaching the switching temperature, in order that, for example, a fan or warning lamp can be switched on.
After cooling down below the reset switching temperature, the contact returns to the original state, so that the monitored equipment can again work normally.
