TSA temperature switches

Ni 1000

These temperature switches are designed for using as two-state controllers (ON/TFF type control). They compare the temperature set-point with the actual temperature value. They cause the galvanically separated (electrically insulated) contacts of a connected relay to switch, when the set temperature is reached. the temperature set point is adjusted by a potentiometer. Switches of the TSA type consist of a plastic connection head carrying the potentiometer control button. Printed circuit boards of the supply and control part of the temperature switch are encapsulated in the connection head. The plastic connection head is made of LEXAN 500R. The temperature switches of this type meet the ingress protection requirements of IP 54 according to EN 60 529.

Regarding sensing element location and switch application the following versions are available:

TSA 220 A - temperature switch for sensing temperature in the switch ambient. The sensing element is placed in the metal stem of the 60 mm length.

TSA 220 K - the sensing element is placed in the metal stem for use in air condition equipment or in tubings. This temperature switch version is available with a plastic mounting clip. Stainless steel thermowell or metal holder can be delivered as an acsessory.

TSA 220 C - the sensing element is protected by the TG 8 case, 40 mm long, and provided with a cable 1 m long. Another case type or another cable length should be specified in the order.

TSA 220 P - contact version switch for fixing on pipeline surfaces for surface temperature measurements. The sensing element is housed in a measuring case made of metal, which is protected by a protection case made of SILIKON and SILAMID. It is delivered with the fastening strap of the length 40 cm and with closure device.

Standard temperature ranges, in which the temperature set point can be adjusted, are given in the specifications table. For the TSA 220 A the maximum allowable operation temperature is 70 °C, for the TSA 220 P this temperature limit is 110 °C. For applications above 120 °C the TSA 220 K may be used. However, in this case the switch version with the stem elongated by 60 mm and the metal centric fixing clip must be used.

These switches are designed to be used in a chemically non-aggressive environment.

Used sensing elements:  Ni 1000/5000.
