Description

The PT-301L pressure transmitter utilizes a piezoresistive sensing principle via its advanced ceramic diaphragm, which deforms under applied pressure to produce a proportional electrical signal. This signal is conditioned by a high-reliability amplification circuit and digitally compensated for temperature effects, ensuring precise conversion to a standard 4-20mA current loop output.

Engineered for demanding environments, the transmitter is built to withstand significant overpressure and features a compact, industrial-grade housing. Its wide operating temperature range and robust construction make it suitable for direct installation in systems monitoring water, oil, air, and other compatible media.

Key Features

  • Robust Ceramic Sensor: 96% alumina core provides high sensitivity, excellent long-term stability, and resistance to corrosive media.
  • Industrial-Grade Signal Output: Standard 4-20mA two-wire current loop ensures noise-immune transmission over long distances.
  • Enhanced Electrical Protection: Integrated reverse polarity protection safeguards the internal circuitry from wiring errors.
  • Advanced Signal Conditioning: Features sophisticated digital compensation technology for full-temperature-zone performance stability.
  • High Overpressure Tolerance: Designed to withstand significant destructive pressure for enhanced safety in critical applications.
  • Wide Operational Envelope: Functions reliably in ambient temperatures from -40°C to 85°C.
  • Compact Form Factor: Enables easy installation in space-constrained applications and systems.

Applications

  • Industrial hydraulic and pneumatic system pressure monitoring and control.
  • Water pump and pipeline pressure regulation in municipal and agricultural systems.
  • Oil and gas process pressure measurement in refineries and chemical plants.

Frequently Asked Questions

What is the output signal and wiring configuration of the PT-301L transmitter?

The PT-301L provides a standard two-wire 4-20mA analog output. The loop-powered design means the same two wires carry both the supply power (11-36V DC) and the output signal. Ensure correct polarity during installation, as the unit includes reverse polarity protection for safety.

What media is the PT-301L pressure transmitter compatible with?

The transmitter, with its 96% alumina ceramic sensor face, is compatible with water, oil, air, and other non-corrosive, non-clogging gases and liquids. It is not recommended for use with highly corrosive or particulate-laden media without additional isolation diaphragms or protective housings.

How do I calibrate or interface the 4-20mA output with my PLC or data logger?

The 4-20mA signal is industry-standard. Connect the output wires to the analog input channel of your PLC, DAQ system, or indicator configured for current loop input. A precision 250-ohm resistor can be used to convert the 4-20mA signal to a 1-5V DC reading for voltage-based inputs. Factory calibration is typically sufficient; field recalibration requires a precision pressure source and a mA meter.
