060G5635 Danfoss Industrial Pressure Transmitter -1 to 5 bar

Product Overview

The 060G5635 (060G5635) is a high-performance industrial pressure transmitter from Danfoss, engineered for precise monitoring in both vacuum and low-pressure applications. Featuring a versatile measurement range from -1 to 5 bar (-14.5 to 72.52 psi), this sensor is ideal for closed-loop control in pump systems, pneumatic circuits, and industrial process lines. The 060G5635 utilizes a standard 4 to 20 mA current output, providing excellent signal stability and noise immunity over long-distance transmissions. With a typical accuracy of 0.5 percent FS and a robust overload rating of 20 bar, it offers the reliability and safety margin required for consistent performance in demanding hydraulic and fluid handling environments.

Technical Configuration

The Danfoss 060G5635 is designed for durability in extreme thermal conditions, maintaining operational integrity across an ambient temperature range of -40 to 100 deg C (-40 to 212 deg F). The device features a G 1/4 male pressure connection following the EN 837 standard, with a 27 mm HEX for secure mechanical installation. Electrical interfacing is handled through a Pg 9 angular connector, providing an IP65 enclosure rating to protect internal components against dust and moisture. The integrated electronics include signal clipping logic (3.6 mA low / 22.4 mA high) to assist in system diagnostics and prevent erroneous control actions during sensor or wiring faults.

Technical FAQs

How does the -1 to 5 bar range benefit vacuum applications?

The -1 bar starting point allows the transmitter to monitor full vacuum conditions. This is essential for applications such as pump suction monitoring, where detecting a vacuum state is necessary to prevent cavitation or to verify that a system has been properly evacuated before charging with media.

What is the purpose of the high and low clipping levels?

The clipping levels (3.6 mA and 22.4 mA) serve as diagnostic thresholds. If a PLC detects a signal at exactly these levels, it can identify a hardware fault—such as a short circuit or a pressure excursion beyond the sensor's physical limits—allowing the system to trigger an alarm or enter a safe state.

Does this transmitter require external calibration?

No. The 060G5635 is factory-calibrated with a fixed zero point and span. While it provides excellent long-term stability, it is recommended to verify the 4 mA output at atmospheric pressure (0 bar gauge) during routine maintenance to ensure no significant drift has occurred due to pressure spikes or environmental stress.

Engineering & Installation Guide

• Mechanical Connection: When installing the EN 837 G 1/4 thread, use the 27 mm HEX surface and apply the specified torque. Use a compatible copper or bonded seal washer to ensure a leak-proof interface. Avoid applying torque to the transmitter body, as this can damage the internal sensing element and housing.

• Wiring and Polarity: Follow the standard pinout: Pin 1 for the positive supply and Pin 2 for the common/signal. To maintain the IP65 rating, ensure the Pg 9 cable gland is tightened correctly around the cable jacket and that the connector's central screw is fully engaged with the internal gasket.

• Media Compatibility: This transmitter is designed for use with a wide range of industrial gases and liquids. However, for highly corrosive or viscous media, verify compatibility with the transmitter's wetted materials. For high-temperature steam, use a cooling siphon to ensure the medium temperature at the sensor face does not exceed 100 deg C.
