Digital Display Pressure Transmitters

-- Steady & Reliable Manufacturer --

Product Overview

Our Digital Display Pressure Transmitters offer the best of both worlds: a highly accurate 4-20 mA or voltage output for control systems (PLC/DCS) and a clear, local digital readout for immediate operator feedback. The integrated display allows for easy field setup, zeroing, span adjustment, and quick troubleshooting without requiring external calibration tools. These units enhance operational clarity and efficiency, making them a preferred choice for modern plant upgrades and localized control loops.

Key Features

Integrated LCD/LED display for local reading.
Simultaneous analog output for remote control.
Push-button menu for zero, span, and unit configuration.

Typical Use Cases

Pump Skids: Local display of discharge pressure for maintenance staff.
Hydraulic Test Benches: High-precision reading with digital stability.
Control Panels: Integrated into local control units (LCUs) for visual status.
Mobile Equipment: Clear, digital feedback for operators in all lighting conditions.
Chemical Dosing Systems: Local confirmation of set pressures before and after dosing pumps.

Competitive Benefits

Field Configurability: Users can change engineering units (psi, bar, kPa) or re-zero the sensor directly at the installation point.
Reduced External Equipment: Eliminates the need for a separate panel meter or analog gauge.
Enhanced Resolution: Digital display offers much finer resolution compared to mechanical gauges.
Error Diagnostics: Many models display error codes directly, simplifying troubleshooting.

Payment and Shipping Details

We accept standard payment methods including T/T and Net 30 days for repeat customers. Shipping terms are typically FOB (Free On Board) or DAP (Delivered at Place). We maintain good stock of common digital transmitters, resulting in a short lead time of 7-10 days. Customized ranges or HART versions may require up to 15 days.

Frequently Asked Questions

Q: Can the display be rotated after installation?
A: Yes, the display module on most models can be physically rotated up to 300∘ for optimal viewing orientation, regardless of the fixed process connection angle.

Q: Is the digital reading the same as the 4-20mA output?
A: Yes, the digital display shows the value measured by the sensor's core, which is the same value converted and sent out via the analog 4-20mA signal, ensuring consistency.

Q: Does the display require a separate power source?
A: No, the display and the transmitter electronics are typically powered by the same 2-wire (4-20mA loop powered) or 3/4-wire supply, simplifying wiring.
