PR-17

Supported Applications

The Omega PR-17 series consists of miniature RTD (Resistance Temperature Detector) connector-style probes designed for liquid temperature measurement. The measuring portion is configured to be inserted directly into a container or fixed in place within pipes, tanks, and vessels using optional compression fittings.

• Liquid temperature monitoring
• Insertion into containers
• Pipe, tank, and vessel installations with "BLRK" or "SSLK" compression fittings

Operating Conditions & Performance

The PR-17 series offers three distinct process temperature ranges depending on the model variant: -50 to 250°C (-58 to 482°F) for Low (PR-17L), -50 to 450°C (-58 to 842°F) for High (PR-17H), and -200 to 600°C (-328 to 1112°F) for Extreme (PR-17E). Accuracy is specified as Class A across the series, with specific ranges defined per model: PR-17L provides Class A; PR-17H offers Class A from -50 to 300°C (-58 to 572°F), or else Class B; and PR-17E delivers Class A from -100 to 450°C (-148 to 842°F), or else Class B.

Response time (T90) varies by model: the 1/8" diameter probe achieves 2.4 sec for PR-17L, 2.8 sec for PR-17H, and 9 sec for PR-17E. The series carries an IP67 ingress protection rating.

Mechanical Ratings

• Vibration: IEC 60068-2-6; 5 to 2000 Hz sweep rate, one active per minute; 10 sweep cycles; acceleration 5g (Duration: 1 day)
• Shock: IEC 60068-2-27; 50g/11ms (Duration: 1 day)

Configuration Options

The PR-17 series is available with PT100 or PT1000 resistance elements, both featuring a nominal resistance of 100 Ω and 1000 Ω at 0°C standard with a TCR = 0.00385 Ω/Ω/°C standard.

Dimensions & Configuration

• Diameter: 1/8" only
• Standard probe lengths: 2, 3, 4, 6, 9, 12, 18, and 24 inches (other lengths available via configurator)

Connections & Accessories

• Electrical connection: Integral male mini connector (female sold separately); heavy duty 3-prong Omega "MTP" connector for easy connection to extension cables or hand-held meters.
• Process connections: Optional "BLRK" or "SSLK" compression fittings available for fixed installation.

Key Product Differences

The series is differentiated by temperature range and model designation:

• PR-17L (Low): Process Temperature Range -50 to 250°C (-58 to 482°F); Accuracy Class A; Response time 2.4 sec.
• PR-17H (High): Process Temperature Range -50 to 450°C (-58 to 842°F); Accuracy Class A from -50 to 300°C (-58 to 572°F) or else Class B; Response time 2.8 sec.
• PR-17E (Extreme): Process Temperature Range -200 to 600°C (-328 to 1112°F); Accuracy Class A from -100 to 450°C (-148 to 842°F) or else Class B; Response time 9 sec.

All models share the same Mini Connector type, IP67 rating, and dimensional constraints (1/8" diameter).
