LF32
LF32
The document outlines the specifications for a series of differential pressure switches, specifically the LF32 model. The pressure range for these models varies from 20-200 Pa to 1000-5000 Pa, with a tolerance of ≤±15% across all models. The media used is air, non-combustible, and non-aggressive gases, with a maximum operating pressure of 10 kPa. The operating temperature range is from -20℃ to +85℃. The switch features a Single Pole Double Throw (SPDT) contact arrangement with an electrical rating of 1.5A (0.4A)/250V. The terminal connection options include a 6.3mm×0.8 blade or screw terminal, and a Φ6.4mm tube connection.
The LF32 model allows for field adjustment of the switch set point without a manometer, using an adjustment knob and a built-in calibrated visual scale. The switch is equipped with a clear cover that provides IP54 protection, preventing involuntary movement of the adjustment knob.
The degree of protection is IP54 with the cover and IP00 without the cover. The document also provides conversion metrics: 1 inch W.C. equals 249 Pa, and 1 mbar equals 100 Pa.
The diaphragm should be mounted in any vertical plane to ensure optimal performance. The document emphasizes the importance of using the clear cover to maintain the IP54 protection level.
The pressure range and tolerances are clearly outlined for each model, with consistent tolerances across all models. The document provides detailed dimensions in millimeters for the LF32 model, ensuring precise installation and compatibility.

Air differential pressure switch The LF32 is an adjustable differential pressure switch capable of detecting miniscule changes in pressure due to the size and proven design. The switch set point or switching point can be f i e l d a d j u s t a b l e w i t h o u t t h e n e e d of a manometer by simply using the adjustment knob and the built in calibrated visual scale.
