United Electric 10 Series Compact Pressure Switch
Description
A compact adjustable pressure switch for OEM and industrial equipment
The United Electric 10 Series is a compact pressure switch with a single SPDT output and an adjustable set point. It is built in an aluminium enclosure and is offered with seven electrical terminations, from push-on terminals (types A and B) to Enclosure Type 4 versions with leads, conduit connection or cable (types C, D, E and G) and an IP65 DIN 43650 connector (type F). Seven pressure ranges, models 10 to 16, cover adjustable set points from 4 to 7500 psi (0.3 to 517 bar), using a diaphragm sensor on the low ranges and a piston sensor on the high ranges. The switch is mounted directly through its pressure connection, and a surface mounting bracket kit is available for field installation, which makes it practical for compressors, pumps, hydraulic and pneumatic circuits and other skid-mounted equipment where space is limited.

Options and ordering
Options listed in the bulletin include a factory-set switch (M201), ranges in kPa, MPa or kg/cm2, intrinsic-safety compliance per ATEX or EAC, a cover lock, EN 10204 material declarations, Viton diaphragm and O-ring, O2 service cleaning, 1/4 in NPT stainless steel or brass connections, SAE and G1/2 threads and a mounting bracket kit. The part number follows the pattern series, termination type, range and options, for example 10 B 11 M201. The bulletin notes that electrical values are based on testing and experience and are not UL rated unless stated on the nameplate, so confirm any approval requirement with the supplier. Please quote the full part number, set point, rising or falling action, media and quantity. Other United Electric items on this site include the United Electric One Series 1XSWLL; see Pressure Instrumentation. The attached bulletin (10-B 06) has the full tables and dimensions.

About brand
United Electric Controls has made pressure and temperature switches since 1931 in Watertown, USA. Instrument technicians usually shorten the name to UE, which is also what appears on many nameplates.
Seven Star LLC lists United Electric pressure switches from the H100 family and the One Series and supplies them to plants in Oman for alarm and shutdown duties.
United Electric pressure switches listed here
Two kinds of UE switch are on this page:
- H100-172, H100-190, H100-361 and H100-376: electromechanical pressure switches from the 100 Series, which the manufacturer builds in a NEMA 4X enclosure. The number after the dash is the model that fixes the sensor type and the adjustable range.
- One Series 1XSWLL: an electronic pressure switch with a digital display, from UE's explosion-proof One Series.
An H100 switch needs no power to operate its contacts. A One Series unit is an electronic device, so its supply and output wiring must be considered when it replaces a mechanical switch.
Where United Electric switches are used
Pressure switches of this kind sit on pump discharge lines, compressor lube oil systems, burner trains, hydraulic units and process vessels. They raise an alarm or trip equipment when pressure moves outside a set limit. In oil and gas, power and water plants across the GCC they are found in alarm and shutdown circuits and on packaged equipment.
Ordering United Electric switches: what we need
A UE model is a string: the type, the model number and then option codes. Send it complete, exactly as on the nameplate, for example H100-190 plus any option codes that follow. If the nameplate is unreadable, give us the adjustable range, the set point and whether it acts on rising or falling pressure, the process connection, the wetted material, the switch output and the enclosure or hazardous-area requirement. For the One Series, the full 1XSWLL code with its range and option suffixes is needed. We check each code against the manufacturer documentation and propose the manufacturer's successor if a model is no longer built.
