Differential Wet Pressure Sensor, 4-20mA/0-5V/0-10V selectable output, 0-7 bar, LCD, BSPT female fittings

PWLX07C $951.15 EA

  • Overview
  • Series Specifications

The PW Series wet/wet pressure transducers incorporate microprocessor profiled sensors for exceptional accuracy and reliability. Easy to use and designed to provide exceptional installation savings, the PWL Series is ideal for measuring pressure across pumps, filters, heat exchangers, compressors, and other non-corrosive wet media applications. The optional LCD display allows easy visibility. The optional pre-assembled bypass valve is designed for easy maintenance and one-step installation.


  • Monitoring and controlling pump differential pressure
  • Chiller/boiler differential pressure drop
  • CW/HW system differential pressure


  • The jumper-selectable output switch for normal (4-20mA) or reverse (20-4mA) operation provides application flexibility
  • Rugged, die-cast enclosure provides NEMA 4 sealing

Exceptional accuracy and stability

  • Dual sensor design for improved overpressure tolerance
  • Jumper-controlled electronic surge dampening for high stability
  • Pushbutton zero calibration – no trim pots to adjust
  • Lowest total installed cost
  • Jumper-selectable port swap feature eliminates costly replumbing when the high and low ports are improperly plumbed...change the jumper position from normal to swap – problem solved!
  • Dual sensor design eliminates the requirement for a bypass valve assembly in most applications
  • Switch-selectable pressure ranges...fewer models to order and stock
  • Pushbutton and remote zero adjustment...maintain accuracy and prevent callbacks with automatic zero calibration
  • Input Power 12 to 30VDC/24VAC nominal
  • Maximum Current Draw DC: 125mA; AC: 280mA
  • Output 3-wire transmitter; user selectable 4-20mA, (clipped and capped)/0-5V/0-10V†
  • Accuracy @ 25°C* Range A, B, C: ±1% F.S.; Range D: ±2% F.S.**
  • Surge Damping Electronic; 5-second averaging
  • Test Mode Overrides output to full-scale (20mA, 5V, 10V)
  • Pressure Ranges (Selectable) 0-0.7/1.4/3.5/7 bar
  • Product Operating Environment -10° to 55°C (-140° to 130°F); 0 to 90%RH, non-condensing
  • Long Term Stability ±0.25% per year
  • Zero Adjust Pushbutton auto-zero and digital input (2-pos terminal block)
  • Status Indication Dual-color LED: Green = Normal, Green Blinking = Low > High, Red = Overrange, Red Blinking = Overpressure
  • Housing Material White powder-coated aluminum

  • Media Temperature Limits -20° to 85°C (-4° to 185°F); 0 to 90% RH non-condensing
  • Fittings 1/8" BSPT female thread, 17-4 PH stainless

†Minimum input voltage for 4-20mA operation: 250 ohm loop (1-5V) = 12 VDC; 500 ohm loop (2-10V) = 15 VDC; Minimum input voltage for volt operation: 0-5VDC output = 12 VDC; 0-10VDC output = 15 VDC. *Accuracy combines linearity, hysteresis, and repeatability.**FS is defined as full span of selected range in bi-directional mode.
