UE H100-193 H100 Series Pressure Switch

The UE H100-193, also cataloged as the H100-193 Pressure Switch, operates as a dedicated hardware component for binary pressure threshold detection within industrial fluid and gas process loops. The device provides direct mechanical-to-electrical execution, converting process pressure changes across a metallic diaphragm into discrete contact state changes.

Process Control and DCS Instrument Loop Integration

The electromechanical switch assembly integrates directly into process control systems via standard 4-20 mA HART loop protocol secondary alarm lines or discrete DCS input cards. Internal physical contacts provide localized channel-to-channel isolation to prevent loop interference when switching independent control networks simultaneously. The dual SPDT contact architecture allows for parallel execution of a physical interlock circuit and a digital status indication feedback loop to the host DCS marshaling panel without electrical cross-talk.

Frequently Asked Questions

Q: Does this mechanical pressure switch require external power to operate the SPDT contacts?

A: No. The H100-193 operates via direct mechanical force. The process pressure acts against the internal diaphragm to actuate the SPDT micro-switches at the designated setpoint without requiring external electrical excitation.

Q: How is channel-to-channel isolation verified between the two SPDT switch elements?

A: Channel-to-channel isolation is maintained via structural physical separation of the internal micro-switch terminals. Each SPDT contact set operates as an independent dry contact, preventing voltage conduction between separate signal loops up to the maximum rated insulation boundaries.

Field Installation Guidelines

NPT Thread Engagement: Apply thread sealant or PTFE tape to the 1/2" NPTF male fitting. Screw the process connection into the pressure port ensuring a minimum of 5 full threads of engagement to meet industrial high-pressure pressure-boundary requirements. Use a wrench on the integrated hex flats only; do not turn the housing.
Electrical Housing Orientation: Mount the enclosure with the electrical conduit entry pointing downward to prevent moisture condensation and process fluids from migrating into the internal SPDT contact chamber via gravity.
Wiring Separation Constraints: Run low-voltage DC signaling loops in separate conduit channels from high-voltage AC electrical lines to avoid electromagnetic inductive coupling across the dry contacts.
Grounding Connection: Terminate the internal green grounding screw to the local plant instrument earth ground network to eliminate static accumulation and ensure physical safety thresholds are maintained.
