DANFOSS PFM5000 measurement needles (pressure sensing probes)

DANFOSS PFM5000 measurement needles (pressure sensing probes) are metal insertion probes designed to provide a direct pressure input for compatible PFM series instrumentation. They enable insertion-based pressure sensing in HVAC, refrigeration and industrial fluid systems, allowing technicians to perform diagnostic checks, leak testing and commissioning tasks where a probe-style connection is required.

Advantages

The metal construction of the PFM5000 measurement needles ensures mechanical durability and stable pressure transmission to the connected instrument. Their probe-style design permits straightforward access to service ports and system lines without complex adapters. These needles are compatible with PFM series pressure inputs and support accurate, repeatable readings when used according to instrument guidelines.

Suitable for

• HVAC system pressure measurements and diagnostics
• Refrigeration circuit testing and leak checks
• Commissioning and performance verification of fluid systems
• Industrial process lines requiring insertion-based pressure sensing

Key specifications

• Probe type: metal insertion pressure sensing needle
• Intended interface: probe-style input for compatible PFM series instruments
• Typical applications: HVAC, refrigeration and industrial fluid systems
• Measurement method: direct insertion for static and stepped pressure checks

How to use

Select a suitable access point on the system where the probe can be inserted without damaging lines or components. Ensure the connected PFM series instrument is powered and configured for external probe input, then carefully insert the measurement needle into the service port or measurement point until a secure, leak-tight fit is achieved. Observe instrument readings and follow standard safety procedures for working with pressurised refrigerants or fluids. After taking measurements, retract the needle and reseal the access point according to system requirements.

Usage recommendations

Use the needle with compatible PFM series instruments and follow manufacturer instructions for connection and pressure range limits. Inspect the probe for signs of wear or damage before each use and avoid excessive bending or impact to maintain accuracy and mechanical integrity.
