Supported Applications

The Omega PR-13 Series consists of Quick Disconnect RTD (Resistance Temperature Detector) probes featuring a heavy-duty, integral male connector. These assemblies are designed for liquid temperature measurement in containers or fixed installation within pipes, tanks, and vessels using optional compression fittings.

Container insertion for liquid monitoring
Pipe, tank, or vessel mounting with 'BRLK' or 'SSLK' compression fittings

Operating Conditions & Performance

The series offers three distinct performance envelopes defined by model family: PR-13L (Low), PR-13H (High), and PR-13E (Extreme). All models utilize a standard TCR of 0.00385 Ω/Ω/°C with nominal resistances of 100 Ω or 1000 Ω at 0°C.

PR-13L Process Temperature Range: -50 to 250°C (-58 to 482°F)
PR-13H Process Temperature Range: -50 to 450°C (-58 to 842°F); Accuracy is Class A from -50 to 300°C (-58 to 572°F), or else Class B
PR-13E Process Temperature Range: -200 to 600°C (-328 to 1112°F); Accuracy is Class A from -100 to 450°C (-148 to 842°F), or else Class B

The probes carry an IP67 ingress protection rating. Mechanical durability specifications include a vibration test per IEC 60068-2-6 (5 to 2000 Hz sweep rate, one active per minute; number of sweep cycles 10 and acceleration 5g) and shock resistance per IEC 60068-2-27 (50g/11ms).

Response Time by Diameter

PR-13L: 1/8" diameter: 2.4 sec; 3/16" diameter: 2.8 sec; 1/4" diameter: 3.25 sec
PR-13H: 1/8" diameter: 2.8 sec; 3/16" diameter: 4.11 sec; 1/4" diameter: 5.41 sec
PR-13E: 1/8" diameter: 9 sec; 3/16" diameter: 9.8 sec; 1/4" diameter: 10.6 sec

Configuration Options

The PR-13 Series is configurable across probe diameters, lengths, resistance elements, and connection types to meet specific installation requirements.

Diameters: Available in 1/8", 3/16", or 1/4"
Standard Lengths: Probes are offered in standard lengths of 2, 3, 4, 6, 9, 12, 18, and 24 inch. Other lengths may be built using the configurator.
Resistance Elements: PT100 or PT1000
Connector Type: Large 3-prong Omega 'OTP' style connector (integral male; female sold separately)
Process Connections: Optional 'BRLK' or 'SSLK' compression fittings for fixed mounting

Key Product Differences

The series is differentiated by the temperature range and accuracy class associated with each model prefix. The PR-13L designation covers low-range applications, while PR-13H supports higher temperatures up to 450°C (-58 to 842°F). The PR-13E variant extends capability for extreme conditions from -200 to 600°C (-328 to 1112°F).
