Great performance for alarm applications The Delta Mobrey Industrial Series was initially created in the mid1990’s. Since that time the range has undergone product developments to ensure we continue to provide industry 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, 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. 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 FEATURES & BENEFITS DOCUMENTATION Better than 1% set-point repeatability Users can expect a set-point repeatability performance better than 1% on all configurations with some configurations being significantly better Extensive range of approvals The Industrial Series switches are available with wide range of different approvals including European and North American Hazardous Area approvals Safety All Industrial Series models come with a safety vent to prevent the enclosure becoming pressurized
