Description

Honeywell 31050381 pH electrode sensor/probe

Product Dimensions：

The Honeywell 31050381 (often associated with the 3100 series of hermetic thermostats) is a high-precision, high-reliability thermal switch designed for demanding environments. Below is a detailed breakdown of its specifications and applications.

Product Overview

The Honeywell 31050381 is a Hermetic Thermostat featuring a snap-action bimetal disc. It is engineered to provide rapid, positive response to temperature changes, ensuring system safety and efficiency. Its hermetically sealed construction makes it ideal for applications where dust, moisture, or atmospheric pressure could interfere with standard switches.

Technical Specifications (Standard Parameters)

While specific custom settings may vary by production batch, the general parameters for this series are:

Key Product Advantages

• Hermetic Durability: The glass-to-metal seal protects the internal bimetal mechanism from oxidation and contamination.

• Precision Snap-Action: Uses a “snap-action” disc that minimizes electrical arcing and provides a crisp, reliable contact break.

• Compact Footprint: Small enough to be integrated into tight spaces in aerospace or industrial machinery.

• High Reliability: Meets or exceeds various military and industrial standards for vibration and shock resistance.

Important Considerations (Precautions)

1. Current Load: Do not exceed the rated electrical capacity. Using this switch beyond its resistive load rating can lead to contact welding.

2. Mounting Surface: Ensure the thermostat is mounted flush against the surface it is monitoring to ensure accurate thermal conduction.

3. Lead Wire Handling: Avoid excessive pulling or bending of the terminal leads, as this can compromise the hermetic glass seal.

4. Application Environment: While hermetic, ensure the external materials (typically steel) are compatible with any corrosive chemicals in the environment.

Common Applications

Because of its ruggedness, the 31050381 is typically found in:

• Aerospace & Defense: Overheat protection in avionics and hydraulic systems.

• Medical Equipment: Precise temperature regulation in sterilization units or lab analyzers.

• Industrial Automation: Thermal management for high-end power supplies and motors.

• Telecommunications: Cooling fan control in outdoor base stations.
