Baumer – PAC50S

Conductivity Meter_IO-Link

Brand : Baumer

The Baumer PAC50S is a compact industrial conductivity sensor and transmitter designed for precise inline liquid analysis in a variety of process environments. Built with robust wetted parts made from PEEK and a stainless steel housing, it supports accurate measurement of liquid conductivity from as low as 1 µS/cm up to 1000 mS/cm with good repeatability and signal stability. The PAC50S integrates both the sensor and transmitter in a space‑saving design and includes IO‑Link 1.1 Dual Channel communication alongside a 4 … 20 mA analog output, enabling flexible process integration, configuration and dual‑channel data capture for conductivity, temperature, and concentration.

Ideal for industrial applications such as water treatment, chemical dosing, and general process control, the PAC50S features programmable temperature compensation, damping and media‑specific concentration calculation via FlexProgrammer or IO‑Link. Its compact form factor and high process temperature tolerance make it suitable for applications with space constraints, frequent cleaning, and variable fluid conditions, delivering reliable performance and rapid response times.
