Overview

The PROVIBTECH PT2060/40-A0 is a single-channel Proximity Signal Processor Module that converts the DC gap voltage from a proximity probe driver into dual 4-20 mA outputs. It separates the input into:

• Static (DC) component – monitors axial shaft position

• Dynamic (AC) component – monitors radial shaft vibration

The /40 code indicates a larger full-scale range (e.g., 0–40 mils peak-to-peak), suitable for machines exhibiting significant shaft movement. Its robust DIN-rail design allows continuous industrial operation while ensuring reliable, standardized analog outputs for both trending and protection systems.

Technical Specifications

Applications

The PT2060/40-A0 is ideal for monitoring large-range shaft movements in heavy industrial machinery, such as:

• Steam turbines with significant axial thrust

• Large centrifugal compressors

• Critical rotating machinery in power generation and petrochemical plants

Its dual 4-20 mA outputs provide continuous real-time data to both control systems and safety systems, enabling trend analysis and supporting protective actions.

Frequently Asked Questions (FAQ)

Q1: Is the PT2060/40-A0 a proximity relay module?

A: No, it is a signal processor. Relay/alarm outputs require a companion module or an E-code variant (e.g., PT2060-E0X).

Q2: What is the purpose of the larger measurement range (/40)?

A: To accommodate machines with wider shaft movements, ensuring the 4-20 mA output spans the full operational range.

Q3: How is the vibration output derived?

A: The module filters the input to isolate the AC (dynamic) component, then conditions and scales it to a 4-20 mA output representing shaft vibration.

Q4: Can the 4-20 mA outputs trigger a safety shutdown?

A: Outputs are for trending. For true API 670 protection, use dedicated alarm relays or specialized safety logic for machine trips.
