REOTEMP Temperature Switches are well-suited to a variety of process applications where electrical devices must be turned on/off in response to changing process temperatures. Solid State Models: The solid state temperature switches are for applications requiring precise monitoring and multiple switch points. These switches provide an extremely long life. The switch is an ideal solution at an affordable price. It has two different configurations: a dual temperature switch or as a single switch with integrated 4-20mA analog output. The switch also has a 10-bit microprocessor that allows for switch time delays and cycling up to 100 times per second.
