Electronics 5343B 2-wire Level Transmitter

The PR Electronics 5343B is a loop-powered 2-wire level transmitter that converts a resistance-type input (e.g., ohmic level sensor or potentiometer) into a standard 4-20 mA current output. It’s designed for accuracy, flexibility and rugged industrial use, especially in level sensing applications. PR Electronics+2Lietuvių+2

Key Features

• Input: Linear resistance (ohmic input) or potentiometer input. Measurement range up to about 0-100 kΩ with a minimum span of ~1 kΩ. Dpstar Group+1

• Output: 4-20 mA current loop standard. Also supports NAMUR NE43 fault signalling (3.5 mA / 23 mA) programmable. Dpstar Group

• Supply voltage: Typical range 8 … 30 VDC for the B-version. PR Electronics+1

• Accuracy: Better than ±0.1% of span (when properly calibrated) for linear resistance input. Dpstar Group+1

• Wide temperature range: –40 °C to +85 °C ambient. Lietuvių+1

• Robust and compact form: Diameter approx. Ø 44 mm × depth ~20.2 mm, weight ~50 g. Easy to mount in a sensor head or on DIN rail (with adapter). PR Electronics

• Configure via PC: The device supports configuration via the “Loop Link” interface and PC software (PReset) including a “PRelevel” tool with linearisation (for e.g., horizontal cylindrical tanks) and online measurement of input span. PR Electronics+1

• Sensor error detection, protection against polarity reversal. Dpstar Group

• Certifications & approvals: A range of approvals including ATEX, IECEx, FM, INMETRO for hazardous area use. Lietuvių+1

Typical Applications

• Converting resistance from level probes or sensors (e.g., resistive level sensors) into 4-20mA signal for integration into your SCADA/DCS or control system.

• Level measurement in tanks (especially where a horizontal cylindrical tank requires volume-linear output rather than just level linear). The linearisation functionality supports this.

• Valve position feedback (since potentiometer inputs also supported).

• Installations in harsh or hazardous industrial environments (thanks to the robust specs and certifications).

• As part of instrumentation systems in chemical, petrochemical, water & wastewater, marine, offshore rigs etc.
