DATA SHEET Pressure Measurement LR056 Pressure Transducer Display LR056 Transducer Display Accurate, Miniature Displays for Point-of-Use Pressure Monitoring Local display of process pressure improves safety and quality control of gas delivery systems. The LR056 allows a sensor to digitally display its pressure and send its signal to a final destination. The sensor, such as the Brooks® SolidSense II® pressure transducer, connects to the back of the LR056 with a 4-pin Bendix® connector. The LR056 connects to the loop through a pigtail cable and offers a real-time reading. The LR056 has two userprogrammable setpoints that define a window; if the window is entered or left, an output signal is generated. Product Features • Local indication of process pressure measurement • 4-digit LED display in durable metal enclosure • Available to display pressure measurement in psia, psig, bar, kg/cm2, or Mpa • Setpoint indication and contact switching available • Password protected • CE (EN 61326) compliant • Programmable via up and down switches • Point-of-use monitoring • Extremely accurate reading with outstanding noise immunity • Low-power electronics • Ease of use and installation Applications Gas delivery systems and tools including: • Gas cabinets • Gas panels • Bulk gas
