Description

Thermostat for Industrial Applications TER

Operating Principle:-

The thermal(thermostat) sensors can be viewed as temperature-dependent pressure sensors. As the temperature increases, the pressure in the sensor system also increases. This pressure change is transmitted to a micro switch by means of a bellows system or a diaphragm. A compression spring provides a counteracting force, whose preload setting can be changed with a set point spindle. The setting of the spindle determines the temperature switch point. Depending on the sensor’s design, adsorption or a tension system will be employed.

Adsorption systems (for all ranges to 50 °C) produce a linear scale with an almost constant differential gap extending over the entire setting range. Tension systems (for ranges between 40 – 90 °C and 80 – 130 °C) are based on the temperature-pressure relationship of a given medium (vapor-pressure curve). A vapor-pressure curve is non-linear, which means that the resulting temperature scale is also non-linear. The differential gaps are different and are based on the switching temperature that has been set. The higher the switching temperature, the smaller the typical differential gap. The average differential gaps are indicated in the device data sheets.

Technical Details:-

Housing: -Aluminium die-cast GD Al Si 12 to DIN1725, resistant to ammonian steam and seawater.

Mounting position:-Optional Max. ambient.

Temperature:-70 °C.

Max. temperature at the sensor:- 70 °C.

Contact: -Single-pole changeover.

Protection:-IP 54 to DIN EN 40050. (in the case of vertical mounting).

Installation: -With TER-H 1 support bracket or with 2 screws (Ø 4 mm) bulk-head mounting.

The adjustment:-Scale value corresponds with the lower switching point (with falling temperature), and the upper switching point is higher by the switching differential.

Plug connection: By means of the obliquely angled plug to DIN EN 175301 (3-pole + earth contact), cable entry Pg 11, max. cable diameter 10 mm. Cable outlet possible in 4 directions (spaced 90 ° apart).

Switching temperature:-Adjustable from outside with a screwdriver

Switching difference:-Adjustable on TER-TRMV for values.
