Brief introduction
1. This model intelligent pressure switch is a kind of intelligent digital pressure control products
2. It integrate pressure measurement, LED display and control.
3. It is complete electronic structure, the former adopt pressure sensor which is diaphragm, oil fulfill and piezoresistive type.
4. Application: Measure the gas and liquid. Suit for pump control, tank monitoring, level control, filter plug, monitoring, leakage monitoring. Also it widely used in hydraulic and pneumatic situation, like mechanical facility and process control.
Main features
1.4 digits display the current pressure value, pressure preset switch point and delay switch output.
2. Switch signal can be set it randomly between zero and full scale. The housing have LEB with node action.
3. Easy to observing key-press calibration and the parameter's setting in field. Convenient operation. The overload capacity is 1.2A for 2 channels switch signal output.
4. Analog output (4-20Ma), the measurement range: 0-600bar (Option)
Most Accurate Control By Electronic Thermal Mass Water Flow Switch
-----------We are gold supplier in 9 consecutive years
CX-FS series Electronic thermal mass flow switch , also known as differential thermal flow sensor and Thermal flow sensor . The set range can be 1-20m/s . Have relay output (230VAC.4A). Suitable for different kinds fluid .Concise and direct indicator ,and with high reliable .
The Principle of electronic thermal mass flow switch based on the principle of thermal theory, there are two resistances in the closed probe . One resistance was heated and regarded as detected resistance , the other one was heated and regarded as standard resistance . When the medium is flowing ,the heat on the heated resistance will be taken away and the resistances' value will be changed . The differential resistances value is the basis of determining the flow velocity .
Application:
gaseous /liquid
The flow switch for ground-source heat-pump is mainly applicable to industrial automation/mechanical equipment/air compressing industry/ refrigeration and air-conditioner. The magnet not contact with flowing water, so can normally work in sewage discharging system.
