Sensors

Contrinex has once again pushed back the boundary of sensing technology with the launch of its new ultra-tiny diffuse fibre optic sensor that has a tip diameter of only 0.5mm making it ideal for detecting extremely small targets or features.

The new MPLS180 sensor from Armstrong Optical Ltd of Northampton is now available allowing the fast, high-resolution 3D scanning of surfaces for all types of applications - ranging from wrinkles on skin to complete, populated, printed circuit boards.

BEI's drawworks encoder is now available with a dual output option. This type of encoder is specifically designed to be use with winch-turns counter in the drawworks system of oil rigs. The dual output allows the encoder to supply simultaneous position feedback to two separate systems from a single encoder. These outputs can even have different resolutions through use of interpolation.

Combining the OxTS RT-Range system with ABD's Autonomous Robots solves the problem of repeatable driving for ADAS (Advanced Driver Assistance System) testing.

The FlexTemp 2301 is a temperature transmitter for Pt100 sensors measuring with an accuracy of only 0.25°C tolerance range. With the universal FlexTop versions 2311 and 2321, the input can be configured for RTD sensors as well as for thermocouples, resistance sensors and current or voltage signals. The universal transmitters have a galvanic isolation between input and output. Their accuracy is at 0.1°C.

Rencol Tolerance Rings has developed a new way of mounting the position sensor magnet accurately and rigidly using a tolerance ring. The new approach presents a simple and cost-effective alternative to the more traditional mounting methods, such as heat to press and the use of adhesives.

A new guide is now available from sensor manufacturer Micro-Epsilon on the company’s non-contact, wear-free eddy current displacement sensors.

A UK-based company is now offering a range of temperature limiters/controllers, pressure transmitters, screw-in transmitters, submersible probes and level control switches, all with SIL2 (Safety Integrity Level 2) approval for hazardous environments.

Wilcoxon Research introduces a new side exit, low profile accelerometer with an integral cable. The 787F is the integral cable version of Wilcoxon’s extremely popular 787A side exit general purpose sensor with a permanent Viton® boot and Teflon® jacketed cable to provide protection in the harshest environments.

One of the main problems with temperature sensors is the ingress of moisture which can seriously affect the sensor performance - the weakest point often being the lead/sensor interface.
