Thermal Sensors

TRS Thermal Reed Switch, Screw Type

Overview

Applications

The TRS Thermal Reed Switch is a highly reliable, precise

temperature-sensitive switch ideal for energy conservation.

The screw mounting package of TRS-P makes it easy to set

up in the application, by just screwing it in the device that

needs temperature detection or overheat monitoring.

Typical applications include radiator water detection

and overheat detection for industrial, agricultural and

automotive engines.

Its unique proprietary design features a magnet and

a temperature-sensing soft ferromagnetic substance

called Thermorite^®. The material’s magnetic ﬂux density

decreases as the temperature increases turning it into a

paramagnetic substance at the Curie temperature.

These products have also been attested by the International

Relay Association.

Structures and Principles of Operation

Thermal Reed Switches (TRS) are temperature-sensing switches composed of a magnet and a temperature-sensing soft

ferromagnetic substance called Thermorite. This material’s saturation magnetic ﬂux density decreases as the temperature

increases, and it turns into a paramagnetic substance at its Curie temperature.

Thermorite properties

• Thermorite changes its magnetic property rapidly at its Curie temperature, providing quick response times.

• The Curie temperature of Thermorite does not vary with time, as it is based on a compounding ratio.

• Thermorite is stable against moisture and hazardous gas.

Structures and Principles of Operation cont.

Reed switch structure

Encasing

• The reed switch is a contact switch comprised of a pair of Fe-Ni alloy

reeds encased in a glass tube with inactive gas. The reeds are switched

on or off by the magnetic ﬁeld of a permanent magnet or magnet coil.

• The reeds in the glass tube become magnetized from the magnetic

ﬁeld, allowing the two reeds to make contact and connect (switch on).

When the magnetic ﬁeld disappears, the reeds separate and disconnect

(switch off).
