Online installation, mechanical flow switch, for liquid or gas medium. Solid plastic, aluminum or

Stainless steel case is optional.

characteristic
Minimal pressure loss, good repeatability, anti fouling ability. The mechanical part is completely separated from the electronic part
It is suitable for small flow economy. 3 times of the original Fe20 piston stroke makes the setting accuracy more accurate.
With switch setting scale, users do not need to set in the field. LED display switch state, double switch output
Available.

application
Gas liquid dual purpose, industrial automation / mechanical equipment / air compression industry / refrigeration and air conditioning
technical parameter
Δ setting range: see parameter table for details
Accuracy: ± 5% of total range
Δ hysteresis: depending on the switching point, the minimum is 0.6l/min
The setting scale of △ switch: it is calibrated when the medium is water and the temperature is 20 ℃
The change of installation position, medium and temperature will affect the switch value slightly
Δ LED display: DC power LED shows switch status, AC has no LED display.
Delta connection mode: M12 connector
Δ output: dry spring switch, capacity: 24 VDC / 250 VAC, 100 mA
△ pressure: 10bar (plastic), 50bar (aluminum), 100bar (stainless steel)
Average pressure loss: 0.3bar (at 25L / min)
Δ medium temperature: maximum 90 ℃
Δ protection grade: IP65

Note: 1. The above parameters in brackets are reset points, while those outside brackets are action points. If the lower limit alarm (monitoring flow is too small), refer to the reset point parameter. The upper limit alarm (excessive monitoring flow) refers to the action point parameters.
2. The above parameters are measured by installing the switch vertically in the horizontal pipeline with 20 ℃ water as medium
