Key Features & Specifications

Why It Matters

• Enables reliable temperature monitoring of heated fluid systems — essential to maintain correct fluid viscosity and flow.
• Protects the thermometer or temperature sensor from mechanical damage or fluid intrusion, extending sensor life and accuracy.
• Ensures sensor mounting is aligned and sealed properly, critical for operational safety and performance in high‑pressure applications.

Installation & Maintenance Tips

• Before installation, depressurize the system and ensure fluid heater is in safe status.
• Mount the housing at the designated location on the heater according to the service manual for correct sensor placement.
• Ensure sealing surfaces are clean, that the sensor fits properly, and that the housing is securely fastened to avoid leaks or sensor misalignment.
• During routine maintenance, inspect the housing for damage, corrosion or ingress of fluid — replace the housing if integrity is compromised.
• Use only genuine 15D757 replacements to maintain fit, sensor alignment and system reliability.
