Overview

The PROVIBTECH PT2060/40-A0-H is a single-channel high-resolution Proximity Signal Processor Module. It converts the DC gap voltage from a proximity probe driver into dual 4-20 mA outputs, separating the signal into:

• Dynamic (AC) component – radial shaft vibration

• Static (DC) component – axial shaft position

The -H designation provides enhanced digital processing and higher resolution, capturing minute changes in shaft dynamics. The /40 scaling allows monitoring of large full-scale movements (e.g., 0–40 mils Pk-Pk), essential for large turbomachinery. Its DIN-rail mountable design ensures robust, continuous operation in industrial environments.

Technical Specifications

Applications

The PT2060/40-A0-H is suited for specialized or large turbomachinery, where:

• Shaft exhibits large or non-linear axial movements

• High-resolution detection of subtle shaft changes is critical

Typical deployments include multi-stage compressors, steam turbines, and large industrial pumps, providing precise data for diagnostic systems (e.g., orbit plotting, spectral analysis) and supporting early-stage fault detection as well as protection of high-consequence machinery.

Frequently Asked Questions (FAQ)

Q1: What benefit does the High-Resolution (-H) feature provide?

A: It allows more precise conversion of the analog sensor signal to the 4-20 mA output, improving the sensitivity of condition monitoring and trend analysis.

Q2: Does the PT2060/40-A0-H include alarm relays?

A: No. The A0 base model provides analog outputs only. Integrated relays require an E-code variant (e.g., PT2060-E0X) or a separate relay module.

Q3: Why is the wide measurement range (/40) necessary?

A: It accommodates large axial shaft movements during startup, shutdown, or normal operation, ensuring the 4-20 mA output covers the full displacement range.

Q4: How are vibration and position outputs generated?

A: The module electronically splits the input into AC (vibration) and DC (position) components. Each is scaled and output independently via its dedicated 4-20 mA current loop.
