Crouzet 79696035 Pt100 Temperature Sensor Equivalent & Substitute Parts

Part Overview

The Crouzet 79696035 is a Pt100 Class B temperature sensor designed for industrial temperature measurement applications with a measurement range of 0 to 200°C. This sensor features a 3-conductor system with exposed lead wires, a 200mm protective steel tube, and 2-meter lead wire length. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Crouzet 79696035 is determined by the following critical parameters:

Element Type Match: Both the main part and substitute must use Pt100 resistance temperature detector (RTD) elements to ensure equivalent thermal response characteristics and measurement accuracy.

Lead Wire Length Compatibility: The 2-meter (6.562 feet) lead wire length must be maintained or exceeded in substitute components to ensure proper installation in existing system configurations.

Terminal Configuration: Exposed lead wire terminals are required for direct connection compatibility with existing wiring harnesses and sensor interfaces.

Temperature Range Consideration: The main part operates from 0 to 200°C. Substitute parts with equal or extended temperature ranges are functionally compatible, as they can operate within the original specification envelope.

Conductor System: The 3-conductor system in the main part provides temperature measurement with lead resistance compensation. Substitute parts using non-grounded conductor configurations remain compatible for temperature measurement applications.

Protective Tube Dimensions: While the main part specifies 200mm length and 6mm diameter, substitute parts with different protective tube dimensions may be used when mechanical installation space permits alternative probe geometries.

Engineering Selection Recommendations

The Omron Automation and Safety E52-P10AEY 2M serves as a functional substitute for the obsolete Crouzet 79696035 based on the following engineering criteria:

Element Type Equivalence: Both components use Pt100 RTD elements, ensuring identical temperature measurement principles and sensor response characteristics across the overlapping temperature range of 0 to 200°C.

Lead Wire Configuration: The 2-meter lead wire length is identical, permitting direct installation in existing system layouts without modification to wiring harness lengths or routing.

Terminal Compatibility: Exposed lead wire terminals on both components enable equivalent electrical connections to measurement instrumentation and control systems.

Temperature Range: The Omron substitute operates from 0 to 250°C, which encompasses the original 0 to 200°C specification. This extended range provides operational margin within the original design envelope.

Product Availability: The Omron E52-P10AEY 2M maintains active product status with current inventory availability, addressing the obsolescence of the original Crouzet component.

Regulatory Compliance: The main part is RoHS Compliant. Verification of regulatory compliance status for the substitute component is recommended during procurement.

Mechanical Considerations: The substitute features a shorter protective tube (100mm versus 200mm) and smaller diameter (3.2mm versus 6mm). These dimensional differences require verification against mechanical installation constraints in the target application.

Frequently Asked Questions (FAQ)

Q: Can the Omron E52-P10AEY 2M directly replace the Crouzet 79696035 in existing installations?

A: The Omron substitute is electrically and functionally compatible based on matching Pt100 element type, identical 2-meter lead wire length, and exposed lead wire terminals. However, the protective tube dimensions differ (100mm length and 3.2mm diameter versus 200mm and 6mm). Mechanical fit verification in the installation location is required before substitution.

Q: What is the significance of the 3-conductor versus non-grounded conductor system difference?

A: The 3-conductor system in the original part provides lead resistance compensation for improved measurement accuracy. The non-grounded configuration in the substitute does not include this compensation. Both configurations are suitable for temperature measurement; the selection depends on the measurement instrument's capability to compensate for lead resistance independently.

Q: Does the extended temperature range of the Omron substitute (0 to 250°C versus 0 to 200°C) affect compatibility?

A: No. An extended temperature range is compatible with the original specification. The substitute can operate safely and accurately within the original 0 to 200°C range. The extended range provides additional operational margin.

Q: Are there any regulatory or compliance considerations when substituting this component?

A: The original Crouzet part is RoHS Compliant. Compliance status for the Omron substitute should be verified during procurement to ensure consistency with system-level regulatory requirements.

Q: What factors should be evaluated before finalizing the substitution decision?

A: Evaluate mechanical fit (protective tube length and diameter), measurement instrument compatibility with the non-grounded conductor configuration, regulatory compliance requirements, and lead wire routing in the installation location. Electrical functionality is compatible based on matching Pt100 element type and lead wire length.
