Crouzet 79696036 Pt100 Temperature Sensor Equivalent & Substitute Parts

Part Overview

The Crouzet 79696036 is a Pt100 resistance temperature detector (RTD) designed for temperature measurement applications spanning 0 to 400°C. This sensor features a grounded design with exposed lead wires and a 30mm protective tube, delivering 2 meters of lead wire length. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this specific model is no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Crouzet 79696036 is determined by the following critical parameters:

Primary Matching Criteria:

• Element Type: Pt100 (resistance value and thermal response characteristics)
• Temperature Range: 0 ~ 400°C (operational envelope)
• Lead Wire Length: 6.562' (2m) (physical installation constraint)
• Terminal Type: Exposed Lead Wires (connection method)

Secondary Compatibility Factors:

• Conductor System configuration (affects measurement accuracy and noise immunity)
• Protective Tube dimensions (affects insertion depth and thermal response time)
• RoHS and regulatory compliance status

The Omron Automation and Safety E52-P10GRY 2M satisfies all primary matching criteria. While it employs a 3-conductor system rather than grounded configuration, and features a 100mm protective tube versus 30mm, these differences represent acceptable engineering trade-offs for applications where the primary thermal measurement range and lead wire length are the controlling specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The Omron E52-P10GRY 2M is the identified equivalent part for the Crouzet 79696036. Both sensors share identical Pt100 element specifications, temperature operating range, and lead wire length. The Omron part is currently in active production status with 1093 units available in inventory, providing supply continuity for applications previously dependent on the obsolete Crouzet model.

Conductor System Consideration:

The transition from grounded to 3-conductor configuration represents a measurement methodology change. The 3-conductor system provides superior error compensation for lead wire resistance variations, particularly beneficial in installations where lead wire lengths exceed standard distances or where temperature measurement accuracy is critical.

Protective Tube Dimension Variance:

The Omron substitute features a 100mm protective tube compared to the original 30mm specification. This extended length affects thermal response time and insertion depth requirements. Applications with strict space constraints or requiring rapid thermal response may require evaluation of alternative candidates or mechanical adaptation.

Compliance Status:

Both parts maintain MSL Level 1 rating (unlimited moisture sensitivity protection). The Crouzet part carries explicit RoHS compliance certification. Regulatory compliance documentation for the Omron part should be obtained from the manufacturer to confirm equivalent environmental standards adherence.

Frequently Asked Questions (FAQ)

Q: Can the Omron E52-P10GRY 2M directly replace the Crouzet 79696036 in existing installations?

A: Direct physical replacement is possible due to matching lead wire length and exposed wire terminal configuration. However, the 3-conductor system requires compatible measurement instrumentation. Verify that your temperature measurement device supports 3-wire Pt100 input before implementation.

Q: What is the functional difference between grounded and 3-conductor Pt100 sensors?

A: Grounded sensors connect the element to the protective tube, reducing electromagnetic noise but limiting error compensation. 3-conductor systems enable lead resistance compensation through a dedicated reference wire, improving measurement accuracy in applications with extended lead runs or high-noise environments.

Q: Does the longer protective tube on the Omron part affect thermal response?

A: Yes. The extended 100mm tube increases thermal mass, resulting in slower response to temperature changes compared to the 30mm original. Applications requiring rapid thermal tracking should evaluate this characteristic against system requirements.

Q: Are both parts suitable for 400°C continuous operation?

A: Both sensors specify 0 ~ 400°C operating range. Confirm with application requirements whether this represents continuous operation or peak temperature exposure, as sustained high-temperature operation may affect sensor lifespan.

Q: What packaging format is the Omron substitute supplied in?

A: The Omron E52-P10GRY 2M is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.
