S20 Pressure Switch – Industrial SeriesGreat performance for alarm applicationsS20 Pressure Switch – Industrial SeriesThe Delta Mobrey Industrial Series was initially created in the mid 1990’s. Since that time the range has undergone product developments to ensure we continue to provide industries with a range of instrumentation dedicated to providing fundamental intelligence within their environment. This range uses diaphragm based sensors and an in-line force balance mechanism to transfer movement from the sensor to the microswitch. All versions of the Industrial Pressure Switch models, S20, S21, and S24, are suitable for a wide range of industrial applications, especially alarm style applications. The S20 Pressure Switch is suitable for setpoints between -1bar and 100 bar with maximum working pressures up to 155 bar. Available in models S21, S22 and S24 (EAC certification is available on request). Key Features - Weatherproof and Flameproof models ATEX and NEC 500.
- NACE MR-01-75 compatibility.
- Ranges available up to 700 bar (10,000 psi)
- Field set point adjustment against a reference scale
- Hermetically sealed microswitch options
- Optional gold alloy contacts
- Terminal block for easy field wiring
- Safety vented design as standard
- PED 2014/68/EU CAT IV option
