Usable for level limit detection in silos with bulk goods. The probe is nearly maintenance free, has no wear, and is very easy to mount on steel silos and steel hoppers. With a modified mounting it is also possible to use in silos made of concrete.
Horizontally-Mounted Accessories Type 2382
Trimod Besta Accessories Trimod Besta Accessories
  • Product Types: 2382, 2383, 28XX
  • Temperature: Up to 752°
  • Material: Carbon Steel
The simplest method of installing any level switch with the standard square flange is to use our standard weld-on counter flange which is available in stainless steel and carbon steel. The test actuator allows a periodic manual function check of the level switch in operating status. Test actuators can be used with all the switches which have square flanges.The use of float chambers allow functional checks and servicing to be carried out without interrupting operation, provided that isolation nad drain valves are included in the process connections.
