ELE-801 Diffused Silicon Pressure Transmitters

Description

Pressure measurement for industrial equipment

ELE-801 transmitters use a diffused silicon sensing element and a 304 stainless steel housing for pressure monitoring in water treatment, industrial pipelines, hydraulic and pneumatic equipment, pump stations and HVAC systems. Select wetted materials compatible with the liquid or gas being measured.

The standard connector version, digital display versions, ELE-801Y cable version and ELE-801K circular connector version share the compact threaded construction. Three-point checks at zero, midpoint and full scale, followed by aging tests, support calibration consistency. The pressure-port design reduces pressure shocks; versions rated above 15MPa use an additional damping structure. Laser-marked housing information provides a durable instrument identification.

Installation and electrical connection

Fit an isolation valve between the transmitter and the process. Depressurize and disconnect power before installation or removal, and apply wrench torque to the hexagonal fitting. Increase pressure gradually, fit a snubber for rapid pressure changes and use a suitable cooling arrangement when the medium exceeds the configured temperature rating. Mount ranges below 30kPa vertically.

For the Hirschmann two-wire current version, pin 1 is loop positive and pin 2 is loop negative. For the three-wire voltage version, pin 1 is supply positive, pin 2 is common negative and pin 3 is signal positive. Use the configuration-specific diagram in the English manual for RS485 and other connector versions. Route shielded signal cable separately from power wiring and keep moisture out of the cable entry.

The attached English catalogue includes the full transmitter range. The English user manual contains selection guidance, dimensions, connector and cable assignments, current-loop and voltage circuits, RS485 connections, installation precautions and service information.
