WESPC Water Temperature Sensor 385720480 For Perkins 403C-11 Engine

Application:

Technical specifications:

Thread M12 × 1.5, hex 19 mm, probe length 48 mm. The sensing element is a negative-temperature-coefficient (NTC) thermistor calibrated 2.5 kΩ ±2 % at 25 °C, falling to 150 Ω ±3 % at 100 °C, delivering a seamless 0–5 V ratiometric signal to the engine control module.

Material & performance features:

The probe shell is precision-machined from lead-free brass and nickel-plated to resist corrosion from glycol-based coolants. The sensing tip is over-moulded in high-temperature PPS, then potted in epoxy for complete immunity to vibration, moisture and electromagnetic interference. A Viton fluorocarbon O-ring guarantees a leak-free seal under 10 bar system pressure, while the robust housing withstands 30 g continuous vibration and 100 g shock.
