Pressure Switch
Pressure Switch
Basic Construction:
- One piece injection molded switch pan Elastomeric diaphragm eliminates the need for an oil barrier
- Field adjustable pressure set points. Factory calibration available upon request
- Built in over pressure protection designed to eliminate stress on other critical operating components
- UL Recognized, Canadian and United States, as an operating, limit or safety control
- Available with CE approved electrical snap switches
Commonly used as an interlock device to sense air, gas or water pressure at a specific point, Series 4000 switches provide on/off control of:
- Electric or gas heaters
- Pumps
- Small air compressors
- Electric strip heaters in VAV systems
- Waste oil heating systems
- Food processing equipment
- Residential boilers
- Other electrical equipment in pneumatic, gas or fluid flow systems
- Maximum Operating Pressure and Hydrostatic burst pressure, varies based on model configurations. Consult factory for specific application needs.
- Electrical ratings to 25 amp, 250 VAC
- Field tested critical components specifically selected to operate reliably in temperature extremes of 32° to 190°F (0°C to 88°C) 100,000+ cycle life under full mechanical, electrical and thermal loads DESigN FLEXiBiLiTY: Tecmark's manufacturing philosophy is unique.
