PR 5115B ATEX Signal Calculator

Description

Please Note: The PR5115B Version has been discontinued
Effective 1 October 2025.

ATEX Certificate of the PR 5115B range has expired and will not be renewed. Contact us directly for the best option for your application.

Application

  • Redundancy measurement of temperature by means of two sensors, where the secondary sensor takes over the measurement when a sensor error occurs on the primary sensor.
  • Duplication of the input signal, e.g. from a temperature sensor or an analogue process signal to two separate analogue outputs.
  • Signal calculator with four arithmetical operations: Addition, subtraction, multiplication and division.
  • Example: Differential measurement: (Input 1 * K1) – (Input 2 * K2) + K4
  • Example: Average measurement: (Input 1 * 0.5) + (Input 2 * 0.5) + K4
  • Example: Different functions on the outputs: Output 1 = input 1 – input 2, and Output 2 = input 1 + input 2

Features

  • Redundancy measurement with 2 input signals
  • Signal calculator with the four arithmetical operations
  • Duplication of the input signal
