- A visible, calibrated dial allows for a quick and simple examination without opening the device, which puts operators in danger.
- With the exception of hermetically sealed snap switch versions, the on/off signal clearly indicates to the operator the condition of any switched equipment that might be placed elsewhere.
- Control applications benefit from adjustable or fixed deadband because it minimizes equipment wear and tear by eliminating needless recycling.
- Setup time is decreased by adjusting the external switch setpoint.
- Application designers can specify standard equipment with pressure ranges from complete vacuum to 8000 psig, which makes installation and training easier and lowers servicing costs.
- CSA approved, UL listed, and FM approved for numerous models to support strict process applications and regulations
- Enclosures that are all-purpose, weatherproof, or explosion-proof that may be used in a range of indoor and outdoor settings and satisfy the demands of many applications
