Conditions withstand pressure: 0 ~ 100bar (high voltage to be customized); medium temperature: -20 ℃ ~ 80 ℃ (medium temperature ≤4 ℃ / s) Ambient temperature Ambient temperature: -20 ℃ ~ 70 ℃; Relative humidity: 5 ~ 85%; Storage temperature: -20 ℃ ~ 60 ℃ control range 1 --- 150cm / s (water) 3 --- 300cm / s (oil) 20 --- 2000cm / s (air) output PNP, NPN The relay power supply voltage external power supply: 24VDC ± 15%, ripple ≤ ± 5% power-initialization response time: ≥8s; Response time: 1..13s, typical 2s control accuracy ± 2.5% of the total drive protection IP65 Connection slip protection electronic work flow switch is mainly applied to the pneumatic and hydraulic systems can be used for circulating water, drying monitoring cutting fluids and lubricants, as well as pumps: threaded or flanged optional) Electronic Flow Switch Applications Principle: based on the thermal principle contains two resistors in closed probes, one of which is heated as the probe resistance, flow switch, and the other was not heated as the base resistance, when the medium flows, the heat is heating resistor is taken away, resistance value is changed, the difference between the two resistors are used as the basis for judging the flow rate of product characteristics of electronic flow switch Features: No moving parts, maintenance-free. Easy installation, a model for multiple diameters requirements. Continuous adjustment switch, thermal flow switch applications, low pressure loss. Compact, LED display flow trend and switch status. 1 Purpose edit the flow switch is based on traffic to the command system of the switch. The flow switch is set to the upper or lower limit, when the flow reaches the limit, the flow switch signal or alarm, the system will run or stop. General requirements for the system will use traffic flow switch. Depending on the system, the electronic flow switch advantages and flow switch type and other factors, are different places, according to the specific circumstances.
