Crouzet 79696037 Pt100 Temperature Sensor Equivalent & Substitute Parts

Part Overview

The Crouzet 79696037 is a Pt100 temperature sensor designed for industrial temperature measurement applications. This component features a 3-conductor system with exposed lead wires, a 50mm protective tube, and operates across a 0–200°C temperature range. The sensor is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and component sourcing in legacy installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Crouzet 79696037 is determined by the following critical parameters:

• Element Type: Must be Pt100 (platinum resistance thermometer, 100Ω at 0°C)
• Conductor Configuration: Must support 3-conductor system for proper resistance measurement and temperature compensation
• Terminal Interface: Must feature exposed lead wires for direct connection compatibility
• Lead Wire Length: Must match 6.562' (2m) specification for installation fit
• Temperature Operating Range: Must encompass or exceed the 0–200°C range to ensure full operational coverage

The Omron Automation and Safety E52-P6FY 2M satisfies all core substitution criteria. While this substitute offers an extended temperature range (-50°C to 250°C) and a longer protective tube (65mm versus 50mm), these differences represent functional enhancements rather than incompatibilities. The extended range provides greater operational flexibility, and the longer protective tube offers improved immersion depth capability.

Engineering Selection Recommendations

The Omron Automation and Safety E52-P6FY 2M is the qualified substitute for the obsolete Crouzet 79696037. Selection is based on:

• Functional Equivalence: Both sensors employ Pt100 elements with identical 3-conductor configurations and 2-meter lead wire lengths, ensuring direct compatibility with existing measurement circuits and signal conditioning equipment.
• Product Availability: The Omron part maintains active production status with confirmed inventory, eliminating supply chain risk associated with the obsolete Crouzet component.
• Compliance Alignment: Both components meet RoHS requirements, supporting regulatory compliance in industrial and commercial applications.
• Enhanced Operational Range: The Omron substitute extends the temperature measurement capability to -50–250°C, providing operational margin beyond the original 0–200°C specification.

Frequently Asked Questions (FAQ)

Q: Can the Omron E52-P6FY 2M directly replace the Crouzet 79696037 in existing installations?

A: Yes. Both sensors share identical Pt100 element specifications, 3-conductor system architecture, 2-meter lead wire length, and exposed lead wire terminals. No circuit modifications or recalibration procedures are required for direct substitution.

Q: What is the significance of the extended temperature range in the Omron substitute?

A: The Omron sensor operates from -50–250°C compared to the original 0–200°C range. This extended capability provides operational margin and allows the substitute to function reliably across a broader temperature envelope without performance degradation within the original specification window.

Q: Does the longer protective tube (65mm versus 50mm) affect installation compatibility?

A: The 65mm protective tube on the Omron substitute provides increased immersion depth capability. In applications where the original 50mm tube was fully inserted, the longer tube will extend further into the measurement medium. Verify that the installation geometry accommodates this additional length.

Q: Are there any compliance or certification differences between the two sensors?

A: Both components are RoHS compliant. The Crouzet part is explicitly RoHS certified; the Omron part's RoHS status is not specified in available documentation. Both carry EAR99 ECCN classification for export control purposes.

Q: What inventory status should be considered when sourcing?

A: The Omron E52-P6FY 2M maintains active production status with 818 units in current stock. The Crouzet 79696037, though obsolete, has 1,048 units available. For new installations or long-term system support, the active Omron component is the preferred choice.
