Description

The process indicator is available with 4 to 20 mA or with HART® protocol. In the HART® version up to 4 measured values of one sensor can be indicated in alternation. For this the indicator can be set as primary or secondary HART® master and actively inquire the values from the sensor. The small voltage drop of < 1V (< 1.9 V with HART®) is a huge advantage especially in Ex-applications, where in most cases only a reduced voltage is available.

Field of application
  • Display of 4 to 20 mA measured values or HART® process variables in all industries
  • Panel-mount housing or field housing as local display
  • Scalable display value
  • With the "Level" or "Analysis" options, basic settings can be made on selected sensors and available measured values and units can be preset quickly and easily.
Benefits
  • Display of 4 to 20 mA measured values or optionally up to four of a sensor's HART® process variables in all industries; Use as primary or secondary HART® master
  • 5-digit measured value display with 17 mm (0.67") character height with dimension and bargraph; backlight can be activated
  • Panel-mount housing (IP65) or field housing (IP66; Ex approval) as local display; Minimal installation depth
  • No external power supply required; Voltage drop ≤1 V (HART® ≤1.9 V)
  • Easy 3-key operation for configuring the device
  • International approvals; marine approval
  • SIL interference freeness acc. to EN 60508
