Set point and deadband are 100% adjustable. No loose parts design, suitable for high vibration environment. There are explosion-proof, intrinsically safe and general-purpose switches suitable for high-risk areas. Comply with SIL 1 & 2 safety system US UE electronic pressure switch applications: • Pumps and compressors - start / stop, optimize treatment, shutdown • Lubricant oil monitoring - oil tank temperature, bearing pressure, pre-maintenance. •Hydraulic oil pressure - high pressure monitoring, emergency shutdown. •Filter Monitoring - Automatic flushing, indication of clogging and abnormal conditions, providing flow values. • Security System - Level 1 & 2 for complete security, alarm and shutdown, on-site alarm switch, fast reaction time.• Plant equipment upgrades – upgrades to power plants and sewage treatment plants to replace mechanical switches. Main technical parameters of American UE electronic pressure switch Accuracy: Repeatability Operating ambient temperature range: At room temperature, the error is 0.5% Repeatability is 0.1% Operating display temperature range: 10°F (-12°C) 158°F (70°C) Response time required for display: 400 ms (2.5Hz) Response time delay: Between 250 ms and 2 seconds, software configured in 2-fold increments. Monitoring (IAW®): Can detect sensor open or short circuit; plugged port; power supply out of range; overload or normal load condition; microprocessor failure; keypad short circuit; switch failure, etc. Output state: 2-state or 3-state operation mode can be selected on site. 2-state operation: (default setting) During normal operation, the output maintains one state (open or closed); i.e. rise/close or fall/close for normally open and rise/open or fall/ open. NOTE: Switches must be normally closed (raise/open, fall/open) during diagnostic tests and other error conditions. 3-state operation: During normal operation, the output remains off; ie rising/pulse or falling/pulse. If it turns on, an error is present; different pulse rates are available depending on the model. Fast or slow type can be selected. See the installation manual for details. Control mode: Field can change the output state, or change the rising or falling setpoint. Automatic or manual reset can be set. Analog output: 4-20mA output, maximum 700ohms 24VDC, field calibrated, 2:1 turn down ratio. Capable of displaying various error conditions at 0, 3.5, 22 and 24 MA ranges. See the installation manual for details. (2WLP, 2XLP,8W2D, 8X2D models) Electrical characteristics: (2-wire models only) Housing: 4X/IP66, aluminum epoxy coated. Dial: Polycarbonate pressure-sensitive keypad and display resistant to UV damage. Cover: Epoxy coated aluminum with tempered glass interior (Ex series models only). Electrical interface: 1/2"NPT internal thread stainless steel interface; 3/4"NPT external thread cast aluminum interface (only explosion-proof series models). Displays: • On-site 4-digit x0.5” LCD • Reset Status • I'm Working (IAW®) • Setpoint • Process Variation • Deadband Value • Switch Evaluation • Min/Max • Switch Status • Error Code Setpoint & Dead zone: user setting, 100% full scale adjustable.Memory : Equipped with a memory that is not easy to lose data to ensure the security of programming and data. Effective transmission distance: 2W2D/2X2D and 2W3A/2X3A can reach 2000 feet effective transmission distance Sensor: Pressure switch - 316 stainless steel welded diaphragm, 1/2" NPT female port. Media Temperature: -40 to 257°F (-40 to 125°C) Differential Pressure Switch - 316 Stainless Steel, Welded Diaphragm, 1/4" NPT male port. Media Temperature: -40 to 257°F (-40 to 125°C) Temperature Switch - 316 stainless steel, 0.25" diameter, 100ohm 4 wire platinum RTD. Media temperature: -300 to 1000°F (-184 to 538°C)Vacuum Resistant: All pressure sensors are vacuum resistant without recalibration. Emission standard: According to EN 55011 class A, EN 61000-3-2 standard emission. EMI/RFI: Compliant with CE, EMC requirements: EN 55011, EN61326, EN61000-6-2 Other functions: EN 61000-3-3 Protection against voltage fluctuations and momentary voltage changes. EN 61000-4-2 Anti-static. EN 61000-4-3 Immunity to continuous radiated interference. EN 61000-4-4 Protection against momentary changes in current. EN 61000-4-5 Shock pressure resistant.
