TYPE 902

TYPE 902

Product catalog summary
Overview: The document provides technical specifications for the Kant Druckschalter GmbH Type 902 adjustable pressure switch, which includes a changeover switch and is designed for various applications with different pressure ranges and materials.
Specifications:
  • Connection: G1/4" Female connection thread/slab connection.
  • Dimensions: 30x30x107 mm.
  • Adjustment Range: Varies from 0.2 – 2 mbar to 40 – 400 mbar, with overpressure safety ranging from 100 bar to 600 bar depending on the model.
  • Reproducibility: Approximately 2-5%.
  • Electricity: Maximum 2A, optionally 10A.
  • Hysteresis: Approximately 20-30%, smaller upon request.
  • Type of Protection: IP 55.
  • Switching Element: Changeover contact.
  • Permissible Temperature: -20° to +100° C.
  • Switching Frequency: 200/min.
  • Weight: 0.38 kg.
  • Voltage: 250 Volt.
Materials and Applications:
  • Diaphragm Sealing Elements: NBR for hydraulic oil, machine oil, heating oil, nitrogen, sea water; FKM (VITON) for hydraulic fluids, petrol, alcohol, salt, and sulphuric acid; EPDM (APTK) for hydrogen, brake fluid, acetylene; SILICONE for food and water.
  • Piston Sealing: Options for oil and hot water.
  • Body Material: ALU or VA 1.4305.
Functionality: The pressure switch operates by deforming a diaphragm or displacing a piston through a lifting movement, which is dependent on an adjustable spring preload. When the switching point is reached, the diaphragm or piston actuates the switch, opening or closing the electrical circuit, allowing specific pressure values to be monitored.
Order Number Example: The order number is structured as ABCD, where each letter represents a specific configuration of the switch.

Catalog excerpts

TYPE 902-1

A Kant pressure switch Type 902 has an integrated electrical changeover switch. When pressure is applied, a diaphragm is deformed or a piston is displaced via a lifting movement. The deformation or movement depends on an adjustable spring preload. When the switching point is reached, the diaphragm or piston has undergone a defined movement which actuates the switch and opens or closes the electrical circuit. Specific pressure values can be monitored via the switching signal.
