Dual-Output Electronic Temperature Sensor — Two Adjustable Switch Points
The Thermal Transfer Products dual-output temperature sensor is an electronic temperature switch that provides two independent switching outputs from a single unit, over a wide measuring range of -13 to 284 °F (-25 to 140 °C). It generates one normally open (NO) and one normally closed (NC) signal, each with a separately adjustable switch point — so a single sensor can trigger two actions at two different temperatures, such as starting a cooling fan at one setpoint and an alarm or second stage at another.
The sensor has a ¼″ NPT process connection for direct installation in a cooler port or fluid line. Sensor port adapters are available to fit a range of ports, and optional bulb wells (thermowells) allow the sensing element to be immersed in the fluid while isolated from it — protecting the sensor and allowing removal or replacement without draining the system.
Its two-setpoint flexibility makes it well suited to multi-stage fan control, staged cooling, or combined control-plus-alarm functions on TTP coolers and cooling packages. TTP Application Engineering can help configure the setpoints and adapters for your application.

Frequently Asked Questions
It’s an electronic temperature switch from Thermal Transfer Products that provides two independent outputs — one normally open and one normally closed — each with its own adjustable switch point, over a -13 to 284 °F (-25 to 140 °C) range.
It lets one sensor control two actions at two different temperatures — for example, switching a fan on at one setpoint and triggering a second stage or a high-temperature alarm at another — reducing parts and wiring versus using two separate switches.
-13 to 284 °F (-25 to 140 °C).
A ¼″ NPT connection. Sensor port adapters are available to fit other ports, and optional bulb wells allow immersed sensing with easy removal.
A bulb well (thermowell) houses the sensing element in the fluid while isolating it, protecting the sensor and letting it be serviced or replaced without draining the circuit.
The Single Set Point Switch is a single fixed on/off contact. This sensor provides two independently adjustable outputs (NO and NC) from one unit — the choice when you need multi-stage or combined control-and-alarm functions.
