United Electric's Explosion-Proof Pressure and Temperature Switches Have New Mounting Flexibility and Increased Safety
Watertown, Ma - United Electric Controls (UE) has improved the popular and proven explosion-proof 120 Series pressure and temperature switches to include the flexibility of dual-conduit wiring and a cover lock to restrict unauthorized access to the wiring and adjustment compartment. All models of the 120 Series are available for immediate delivery from UE's factory or network of stocking distributors located throughout the world.
The 120 Series carries cULus and Cenelec worldwide agency approvals for usage in hazardous locations, and meets CE and PED pressure equipment directive. Wiring to an accessible terminal block provides customers with both convenience and cost-effective installation. The extensive line covers all applications for explosion-proof instrumentation. A broad selection of pressure ranges, wetted materials and pressure port configurations cover from vacuum to 6,000 psi / 414 bar. Differential pressure models start at low pressures of 0.2"WCD, and extend to 500 psid / 34 bar. Temperature twitch models have a choice of remote bulb & capillary sensing or local immersion stem, and rover ranges from -180F to +650F (344°C). The availability of single or dual outputs provide reliable threshold detector, and switching for alarm, pre-alarm and high/low trip points.
The wide selection of specifications coupled with the rugged epoxy-coated type 4X enclosure make the 120 series the line of choice in chemical, industrial gas and petrochemical plants, refineries, oil and gas production and pipeline transmission applications. UE's 120 Series leads the world in protecting equipment, processes and personnel in rugged industrial and hazardous atmospheres. Key options help meet the most challenging applications: hermetic seal switching for corrosive environments; indicating differential pressure models for filter monitoring; hastelloy, monel and tantalum sensors to match corrosive media.
