Digi-Stem® Advanced Digital Process Pressure Gauge

The NEW Digi-Stem® Advanced Pressure Gauge has accuracy of 0.1% of Full Scale in Relative Gauge, Absolute, Compound, Vacuum, and Barometric Pressure Types.

Description

The Digi-Stem® Advanced Digital Pressure Gauge is an extension of our perenially popular Digi-Stem® Temperature Systems.  Housed in a rugged stainless steel enclosure, the DSP is IP68 Compliant and NEMA 6P rated to prevent water ingress.  Additional protection against EMI and RFI prevents external electromagnetic signals from effecting the functioning of the unit.

Accuracy is 0.1% of Full Scale in Relative Gauge, Absolute, Compound, Vacuum, and Barometric Pressure Types, in ranges from -15 to 15,000 PSI.  Easy to read 0.9 inch high primary display shows real time pressure reading on the easy to read backlit screen. The secondary display shows Max, Min, Avg, or Delta in 0.4 inch high digits. Use the percent of Pressure Range indicator on the screen to safely prevent overrange. If maintaining 0.1% accuracy from 0° to 50°C is a must, add our 9-Point NIST Certificate of Conformance at time of purchase.

Battery powered models also feature exceptionally long battery life. The C cell Lithium Metal Battery has a life of up to Four years at the default one second refresh rate.  Monitor the remaining battery life with the icon on the display, and change the refresh rate to meet the needs of your process.

Options:

Add the optional Transmitter and Switch to your DSP unit to gain additional functionality, including a loop powered 12 - 24V DC powered Pressure Transmitter with analog 4-20 mA or 0-5 V output. Pressure Switch is 12 - 24V DC loop powered and has a consistent Open Relay, with the option to trigger the switch at Low and High Alarm points. Program two pressure points to switch from ON to OFF; works with polarized, safety, solid-state, and time delay relays.  Advanced visual alarms are fully adjustable: High alarms have Red Backlight and screen icon, while Low alarms have Blue Backlight and screen icon. Normal readings have a Green Backlight.

Advanced capability allows this gauge to run multiple functions simultaneously, with data flowing to the display, transmitter, switch, and alarms at the same time.  Continuous self-checking technology consistently verifies the accuracy of twelve critical factors for the electronics and the sensor. This also indicates any out-of-tolerance conditions, ensuring the accuracy and ability to punction properly during processing are not compromised.

Additionally, choose between Fixed and All-Angle mounting type. Unique All-Angle mount option allows for installation in almost any location, adjustable for the best viewing angle.

Available with 3 Point or 9 Point NIST Traceable Certificate of Conformance.  9 Point NIST Traceable Certificate of Conformance provides 0.1% accuracy at 0° to 50°C.

Manufactured in our Asheville, NC, USA facility.
