Product Highlights

  • Non-linear Signal Correction
  • Four Configurable Alarms
  • Signal Bar Graph Display
  • Powered by 4-20mA Loop
  • Intrinsically Safe
  • Wall, Pipe and Panel Mounting
  • Watertight to IP67 (Nema 4X)
  • ATEX, IECEx, CSA Approved
  • CE Compliant


  • Contrec 250 is a high accuracy, Intrinsically Safe Process Indicator especially for operating with digital output transducers
  • Therefore 250i is perfect for the most arduous of installations; this is because it is having an IP67 weatherproof case, new tactile keyboard, and various mounting options.
  • Contrec 250 Programmable Process Indicator accepts a 4-20mA signal from a wide range of transducers. For example, pressure or temperature transmitters, weigh scales, pH sensors, flowmeters or level transmitters.
  • Solid state relay outputs provide up to four level alarms and a 25 point non-linearity correction table. Hence, the process indicator can be programmed for non-linear signals.
  • The power source for this process indicator is entirely from the 4-20mA current loop. Therefore, requires no external power or batteries.
  • The instrument is fully programmable with setup parameters. For examples, span, offset, alarm levels, etc., stored in a non-volatile memory which will retain all data for more than ten years without power.
  • Contrec 250 enclosed in an attractive IP67 (NEMA 4X) polycarbonate enclosure.
  • Therefore, the process indicator is entirely watertight.
  • The process indicator comes with a standard wall mounting bracket. Meanwhile, the process indicator is having options for panel mounting and 2″ pipe mounting.
  • The LCD Signal Bar display on Contrec 250 Process Indicator measure and display signal as a percentage (0 – 100%), while up to 7 Digit numeric display for the process variable.
  • The Indicator will display the signal level on the bar graph and the scaled process variable on the large numeric display.
  • The operating temperature for the process indicator is -20°C to +60°C or -4° F to +140°F.
  • The dimension for the process indicator is 98mm(H) x 151mm(W) x 43mm (D).
