TS350-4 Fireye Sensor

Overview

The Fireye TS350-4 is a precision immersion-style temperature sensor designed for industrial and commercial burner management systems. It provides accurate monitoring of water, stack, or boiler temperatures by converting thermal readings into a linear 4-20 mA analog signal. Engineered for durability, it comes equipped with a 4-inch stainless steel thermowell to protect the sensing element from high-pressure and corrosive environments while ensuring efficient heat transfer for responsive data collection.

Features

• High-precision platinum 100-ohm RTD sensing element for stable and reliable temperature detection.
• Linear 4-20 mA output signal facilitates easy integration with modern control systems and minimizes electrical interference over long distances.
• Rugged 300-series stainless steel thermowell included for enhanced protection and longevity in demanding applications.
• Integrated design requires no field setting or calibration, simplifying installation and maintenance.
• Continuous safety monitoring when used with compatible Fireye controllers to detect under-range, over-range, or open wiring conditions.
