Maxitrol TS394-3B-48FQ Sensor

The Maxitrol TS394-3B-48FQ is a high-precision Series 94 Stainless Steel Sheath Sensor designed specifically for integration with the AD1094 advanced data logger. As a veteran in the field, you know that accurate BTU calculation in commercial and industrial gas-fired systems depends entirely on the reliability of your temperature inputs. This 1,000 ohm RTD (Resistance Temperature Detector) provides the thermal sensitivity required for Selectra Series 92 and 94 systems, ensuring optimal modulation of direct or indirect fired units. Featuring a durable 3-inch by 0.19-inch diameter stainless steel probe and a 48-foot lead length, this HVAC temperature sensor is built to withstand demanding boiler and furnace environments. It serves as a direct replacement for the TS394-3B-72Q and is essential for BTU monitoring and energy management. Whether you are performing a field installation on existing equipment or specifying for a new build, this Maxitrol replacement sensor delivers the consistent NTC thermistor performance needed to maintain tight control over water or air temperatures up to 30,000,000 BTU.

• System Compatibility: Fully compatible with Maxitrol AD1094 data loggers and Selectra Series 92/94 configurations.
• Robust Construction: Features a corrosion-resistant stainless steel sheath sensor for long-term deployment in harsh HVACR environments.
• High-Capacity Precision: Engineered to provide accurate data for systems with capacities up to 30,000,000 BTU.
• Direct Replacement: Simplifies maintenance by serving as the standard replacement for the TS394-3B-72Q sensor.
