Automation Products Group's PG7 digital pressure gauge features a five-digit display for outdoor applications

Automation Products Group Inc. introduces the PG7 digital pressure gauge. Specifically engineered for challenging outdoor conditions, the IP67-rated PG7 features a full five-digit display with 0.4-inch characters that leverage MEMS-based sensing technology for maximum reliability and stability. 

The PG7 is available with ranges from vacuum to 500 psi, and from 0 to 10,000 psi, at ±0.25% accuracy of full scale (B.F.S.L), while delivering .01-digit resolution as standard through 100 psi. The unit incorporates a stainless steel sensor that is resistant to most typical vibration and shock exposures. The PG7 provides highly accurate readings even with pulsating pressures.

PG7 digital pressure gauges feature a microprocessor-based circuit with Tare, Peak Hold and Max-Min capabilities to enable users to set the gauge to meet specific application needs. User-selectable functions include:

  • Auto-off (2, 4, 8, 16 or 32 minutes)
  • Maximum and minimum readings
  • Units of measurement (psi, bar, mbar, kPa, MPa, inH2O, mmHg, inHg, cmHg, kgcm2 or ftH2O)
  • Units of force for press applications to directly display the applied force

The PG7 is available with three different power options. A self-powered version uses two AA batteries with a typical battery life of 2,000 hours using alkaline cells. Self-powered units are available with no output (display only), or with a 0-2 VDC output. Externally powered versions operate on 9-28 VDC, and are available with display-only output and 0-5 VDC output options. Each of the externally powered versions is available with two optional solid state relay trip-point outputs for alarm or control purposes. The PG7 is also available in a 4-20 mA loop-powered version.

Units are available with absolute, sealed or vacuum pressure references; a rear pressure port; and up to ±0.1% full scale accuracy (B.F.S.L) with NIST certification (on selected ranges). Other units of measurement and process connection fittings are also available.
