Product Details

The Fireye TS752-4 is an immersion platinum temperature sensor from the TS752 series, fitted with a 4‑inch stainless steel thermowell for boiler and stack temperature measurement. This temp sensor adopts platinum positive temperature coefficient element and outputs linear 4‑20 mA analog signal, designed to pair with Fireye BurnerLogiX burner management system and Nexus PPC4000 fuel‑air ratio controller. As a reliable transmitter, it requires no on‑site calibration after installation and delivers stable readings for flue gas, boiler water and process fluid temperature. This probe is stocked as genuine replacement spare part for combustion control systems.

Supported Functions

This immersion probe captures real‑time temperature and converts it into standard 4‑20 mA signal for the main burner controller. It continuously feeds temperature data to support fuel‑air ratio trimming, overheat protection and boiler condition monitoring. If temperature exceeds the set threshold, the host control can trigger alarm or safety shutdown.

Core Functions

The platinum sensing element provides high repeatability across the full working range. The integrated stainless steel thermowell protects the sensor from corrosion, soot and high flow velocity. It can be directly installed into boiler shell, flue stack or piping and supports drop‑in replacement for existing TS752‑4 sensors.
