Product Details

The Fireye TS350-8 is an immersion platinum temperature transmitter from the TS350 series, fitted with an 8‑inch stainless steel thermowell for low‑to‑medium temperature measurement. This immersion temperature sensor adopts a platinum PTC sensing element and provides linear 4‑20 mA analog output, designed for Fireye BurnerLogiX burner management and Nexus PPC4000 fuel‑air ratio controllers. As a reliable 4-20mA transmitter, it comes factory calibrated and requires no field adjustment, suitable for boiler water, mild stack gas and process fluid temperature monitoring. This combustion 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. Once temperature exceeds the preset threshold, the host control can trigger alarms or safety shutdown.

Core Functions

The platinum sensing element delivers stable, repeatable readings within its rated range. The integrated stainless steel thermowell protects the sensor against moisture, light soot and fluid erosion. Its longer insertion length suits large vessels and deeper piping installations, and it supports drop‑in substitution for existing TS350-8 sensors.
