Series-TRI2-TRIDICATOR

Supported Applications

The Dwyer Series TRI2 Dual Pressure & Temp Tridicator Gage combines a pressure gage and thermometer into a single instrument. Designed to simplify installation, the series is intended for use with compatible gases and liquids where simultaneous monitoring of process conditions is required.

Operating Conditions & Performance

The Series TRI2 operates within an ambient temperature range of -40 to 250°F (-40 to 120°C) and a process temperature range of 80 to 290°F (30 to 140°C). Accuracy is specified as Pressure ±3-2-3% and Temperature ±1 scale division. The instrument features a moveable dial with blue pressure markings and red temperature markings, indicating pressure in both psi and kPa while measuring temperature in Fahrenheit and Celsius.

Configuration Options

The series is offered across three measurement ranges: 0 to 60 psi (0 to 400 kPa), 0 to 100 psi (0 to 700 kPa), and 0 to 200 psi (0 to 1400 kPa). Configuration options include distinct mounting styles, process connections, and dimensional profiles.

Mounting & Process Connections

• Center back mount with extension shank: Features a 1/4" male NPT connection (e.g., TRI2-60-25E).
• Center back mount: Features a 1/2" male NPT connection.
• Bottom mount: Features a 1/2" male NPT bottom connection.

Housing & Wetted Materials

• Housing material: Drawn steel with black finish.
• Wetted materials: Brass connection and phosphor bronze Bourdon tube.

Dimensions & Weight

Overall dimensions vary by mounting configuration. Center back mount and lower mount models weigh 12.35 oz (350 g), while center back mount with extension shank models weigh 14.11 oz (400 g). Specific dimensional values for parameters A, B, and C are provided in the specification grid.

Calibration Options

NIST traceable calibration certificates are available as options:

• Pressure: Order code NISTCAL-PG1.
• Temperature: Order code NISTCAL-TG.

Key Product Differences

Variants within the Series TRI2 are distinguished by their pressure range and mounting configuration, which dictate process connection size and overall physical dimensions. Models ending in "-25E" utilize a 1/4" back mount with an extension shank. Models ending in "-50" feature a standard 1/2" back mount, while models ending in "-50L" are configured for bottom mounting with a 1/2" connection.
