Pressure Transmitters...
The differential pressure switch has a synthetic spring suspended membrane which is linked to a changeover contact. When the differential pressure exceeds the setpoint value the contact changes. The differential pressure switch is used to supervise and monitor fans, filters and air handling units, to control defrosting functions etc.
Regin pressure and differential pressure transmitters use a ceramic measuring beam. The differential pressure affects a membrane taht works directly against the measuring beam with film resistor. When the resistance changes it is converted to a proportional output control signal.
• High degree of accuracy
• Few moving parts - rapid response
• Excellent long-term stability
The air velocity sensor operates with a specially designed thin-film element which is heat (the hot-film anemometer principle). The cooling rate of the element, which depends on the air velocity, is measured and transformed to an output signal proportional to the air speed.
• Stable output signal compensated for varying temperature
• Extremely high frequency response. Not sensitive to contamination by dust etc.
The flow switch operated by an electrical blade-type tripping device interrupts the electric control circuit of the boiler/chiller when there is insufficient water circulation in the boiler/chillerpipe owing to some abnormal condition.
