Barksdale L2H-H203-W Temperature Switch 75-200F

Product Description

The BARKSDALE L2H-H203-W is a local-mount temperature switch designed for industrial and commercial sensing applications where reliable temperature-triggered switching is required. The unit covers a sensing range of 75 to 200 degrees F and uses a rigid stem configuration with a brass stem measuring 13/16 inches by 3-1/8 inches. It connects via a 1/2-inch NPT process fitting. The dual set point SPDT contact form allows a single switch to control two independent switching events within the operating range, reducing the need for multiple devices on a circuit. Licensed instrumentation technicians and industrial HVAC or process-control mechanics are the typical installers.

This temperature switch suits local-mount installations in commercial HVAC systems, industrial process piping, and fluid-handling equipment where immersion-style temperature sensing and direct switching output are needed. Its brass rigid stem makes it appropriate for water, oil, and compatible fluid media. The local-mount housing allows for direct visual indication or field adjustment at the point of installation without remote instrumentation. The 1% of mid-60% of full-scale accuracy specification suits process monitoring and equipment protection applications.

Key Features

• Sensing range of 75 to 200 degrees F covers common process and HVAC fluid temperatures
• Dual set point SPDT contact form provides two independent switching outputs in one device
• Rigid brass stem construction for durability in liquid immersion service
• 1/2-inch NPT connection for standard pipe and well installations
• Local-mount design allows direct field access for adjustment and visual status
• Accuracy of 1% of mid-60% of full scale for reliable process control

Compatibility

Designed as an OEM-style replacement or direct installation temperature switch for commercial and industrial systems requiring a 1/2-inch NPT rigid-stem immersion switch with SPDT dual set point output in the 75 to 200 degrees F range.

Installation Notes

Installation should be performed by a licensed instrumentation technician or qualified mechanic familiar with process control wiring and NEC low-voltage switching requirements. Shut down and depressurize the fluid system and de-energize all associated control circuits before removing or installing the switch. Use an appropriate thermowell or direct-immersion fitting that matches the 1/2-inch NPT stem connection. Do not exceed the rated temperature range of the switch during system commissioning or operation.
