Fucusens Solution

The FHR400 Series is a compact NTC temperature sensor designed for temperature measurement in medical warming blankets and compatible monitoring equipment. Its small PVC-encapsulated sensing tip supports installation where limited space and short thermal response are required.

The standard configuration uses a 2.252KΩ NTC thermistor with a B25/85 value of 3976K. Thermistor specification, probe dimensions, cable length and connector can be customized according to the equipment interface and temperature-control requirements.

Feature	Description
±0.2°C Temperature Tolerance	Supports temperature measurement from +25°C to +45°C with a specified tolerance of ±0.2°C.
Compact Sensing Tip	Approximately 1.9 × 7 mm probe tip fits space-limited installation positions.
Fast Thermal Response	Thermal time constant of ≤7 seconds in flowing water at 0.4 m/s.
2.252KΩ NTC Thermistor	Standard 2.252KΩ resistance with B25/85: 3976K for compatible monitoring equipment.
Custom Cable and Connector	Probe dimensions, cable material, cable length, resistance value and connector can be customized.

Typical Applications

Application	Description
Medical Warming Blankets	Measures temperature for warming blanket monitoring and control systems.
Patient Warming Systems	Provides temperature feedback for medical warming equipment.
Temperature Monitoring Equipment	Compatible with monitoring equipment using a matched 2.252KΩ NTC input.
Medical Heating Pads	Supports temperature measurement and over-temperature control.
Clinical Temperature-Control Equipment	Customized probe, cable and connector options support equipment integration.

Product Structure & Selection Guide

NTC Thermistor

The 2.252KΩ thermistor provides a defined resistance response to temperature changes.

PVC-Encapsulated Probe

The compact encapsulation electrically insulates the thermistor while keeping the sensing tip small.

Flexible Cable

The cable transfers the resistance signal to the connected controller or monitoring equipment.

Strain-Relief Section

The reinforced transition area reduces mechanical stress where the probe lead connects to the main cable.

DC Plug Connector

The connector supports convenient connection to compatible monitoring or temperature-control equipment.

Is this sensor compatible with YSI 400 Series inputs?

The 2.252KΩ configuration is intended for systems using a corresponding NTC input curve. Compatibility must be confirmed against the equipment manufacturer’s resistance–temperature curve, connector and pin definition.

Can a 10KΩ NTC thermistor be used?

Yes. A 10KΩ option can be developed according to the controller requirements.

Can the cable length and connector be changed?

Yes. Cable length, material, connector and strain-relief structure are customizable.

Is this a disposable or reusable sensor?

This should be defined according to the selected materials, equipment design, cleaning method and applicable medical-device requirements.

Can you manufacture from an existing sample?

Yes. A customized version can be developed from a drawing, technical specification or reference sample.
