Product Overview

The 060G1475 (060G1475) is a rugged industrial pressure transmitter engineered by Danfoss for precise liquid and gas pressure monitoring in heavy-duty environments. This sensor features a measurement range of 0 to 10 bar (0 to 145.04 psi) and utilizes a standard 4-20 mA current output signal, ensuring high noise immunity over long cable runs. Designed for versatility in hydraulic systems, air compressors, and water treatment plants, the 060G1475 provides a reliable gauge (relative) pressure reference. Its robust construction supports an overload pressure of up to 60 bar, protecting the internal sensing element against sudden pressure spikes and water hammer effects, thereby extending the service life of critical automation infrastructure.

Technical Configuration

The Danfoss 060G1475 is built for survival in extreme thermal conditions, maintaining operation from -40 to 100 deg C (-40 to 212 deg F). The device features a G 1/4 male pressure connection following the DIN 3852-G standard, with a 27 mm HEX for secure installation. Electrical interfacing is handled via a Pg 11 angular connector, providing an IP65 enclosure rating to protect against dust and low-pressure water jets. The circuitry includes signal clipping logic, with high clipping at 22.4 mA and low clipping at 3.6 mA, which aids in sensor health diagnostics. With a typical accuracy of 0.5 percent FS, this transmitter provides the high-fidelity feedback required for closed-loop control systems without the need for manual zero-point or span adjustments.

Technical FAQs

How do the high and low clipping levels assist in system diagnostics?

The high clipping level (22.4 mA) and low clipping level (3.6 mA) allow the PLC to distinguish between a valid pressure reading and a hardware fault. For instance, a signal drop below 3.6 mA typically indicates a wire break or sensor failure, while a signal above 20 mA but capped at 22.4 mA indicates an over-pressure condition still within the sensor's electronics range.

Is this transmitter suitable for applications involving steam or high-temperature media?

While the transmitter is rated for ambient temperatures up to 100 deg C, the media temperature must also be considered. For steam applications, a cooling siphon (pigtail) should be used to protect the sensing diaphragm from direct contact with high-temperature steam that exceeds 100 deg C.

Does the 060G1475 require periodic recalibration?

This model is designed with a fixed zero point and span. While it provides excellent long-term stability, it is best practice to verify the 4 mA output at atmospheric pressure annually to ensure the sensor has not experienced significant drift due to extreme pressure cycles or vibration.

Engineering & Installation Guide

• Mounting Torque and Sealing: When installing the G 1/4 connection, use the 27 mm HEX and apply appropriate torque to ensure a leak-proof seal. Since this follows the DIN 3852-G standard, ensure the sealing face is clean and utilize a compatible gasket or O-ring. Avoid over-tightening, which can deform the sensing diaphragm and cause permanent zero-shift errors.

• Wiring and Electrical Safety: Connect the + supply to Pin 1 and the - common to Pin 2 of the angular connector. To maintain the IP65 rating, ensure the Pg 11 cable gland is tightened securely around the cable jacket and the connector screw is fully seated with the gasket in place.

• Pressure Spike Mitigation: In hydraulic systems where fast-acting valves are present, pressure spikes can exceed the 60 bar overload rating. It is recommended to install a pressure snubber or restrictor in front of the 060G1475 to dampen these transients and protect the sensing element from mechanical fatigue.
