The Vemo V95-72-0025 is a precision-engineered coolant temperature sensor designed for automotive and industrial applications where accurate monitoring of liquid cooling systems is critical. This sensor delivers reliable performance across a wide range of operating temperatures, ensuring optimal engine protection and efficient thermal management.

Key Functional Characteristics

• Temperature Range: Operates effectively from -40 °C to +120 °C, covering the extremes encountered in modern combustion engines and high-performance machinery.
• Output Signal: Provides a linear voltage output proportional to temperature, typically ranging from 0.5 V at 0 °C to 4.5 V at 100 °C, compatible with standard engine control units (ECUs) and data acquisition systems.
• Response Time: Rapid thermal response due to a compact sensor body and high-conductivity materials, enabling real-time temperature monitoring during transient operating conditions.
• Durability: Constructed from corrosion-resistant alloys and sealed with a robust epoxy encapsulation, the sensor withstands aggressive coolant chemistries and mechanical vibrations.

Design & Construction Details

The V95-72-0025 features a toroidal sensing element that maximizes surface contact with the coolant while minimizing flow disturbance. The sensor housing is made from stainless steel 316L, providing excellent resistance to rust and chemical attack. An internal hermetic seal ensures no leakage of coolant or ingress of contaminants, preserving signal integrity over extended service life.

Installation Guidelines

• Mounting: The sensor is designed for direct insertion into the engine block or cooling system manifold. It includes a threaded interface (M6 x 1.0 mm) that matches standard automotive coolant passages.
• Connection: A shielded cable with a 4‑wire configuration (power, ground, signal, reference) is supplied to reduce electrical noise and maintain accurate readings.
• Calibration: Prior to first use, the sensor should be calibrated against a certified temperature reference. Calibration procedures typically involve placing the sensor in a controlled bath at known temperatures and adjusting ECU parameters accordingly.
