High-precision tension, pressure and flow control applications

version has four thermocouple inputs, two of which can optionally be configured for use as standard analogue inputs (1 to 5 V, 0 to 10 V, or 4 to 20 mA). This version allows temperature sensing and analogue sensing to be combined cost effectively in a single unit. Both units deliver high accuracy and performance, and they are complemented by Omron’s PID function block and CX pro- grammer, which make it easy to implement temperature control systems.

The new analogue I/O units from Omron offer a conversion resolution of 1 part in 12 000, making them an ideal choice for high-precision tension, pressure and

flow control applications, and for use with measurement sensors in quality inspection systems.The units available are input-only versions with four analogue inputs, output- only versions with four analogue outputs and mixed I/O versions with four analogue inputs and either two or four analogue outputs. All versions support the full range of standard current and voltage signals. Omron’s new temperature sensors are offered in two versions.The first has twelve inputs for use with thermocouples, and is well suited for use with extrusion mould- ing machines and large ovens.The second

Photoelectric sensors with PMD technology – and Laser Class 1 The tried-and-tested photoelectric O5D sensors from ifm electronic are distinguished by switch point set- ting to the nearest centimetre, colour-independent detection and reliable background suppression. The PMDLine series even detect shiny surfaces without any difficulty. ifm has now extended this sensor family with laser class 1 allowing it to meet the requirements of applications in the automotive industry. In its compact housing, the O5D variant combines long range, reliable background suppression, visible red light and high excess gain – plus laser class 1. Another advantage is its ease of use and switch point setting to the nearest centimetre via +/- buttons and display.The O5D family is an intelligent alternative to standard sensors, since their price and size are in the same range.
