Advertorials Sensors for Extreme Temperature Conditions


Available from ATC Semitec Reliable thermal protection is critical for machinery or equipment that is operating at extreme temperatures. Failure at either extreme can be critical. Hereaus Nexensos, manufacture a range of platinum film sensor PRTDs (Pt100) which with key characteristics of linearity, reliability and stability reinforce their suitability of their use in extreme conditions. The Heraeus thin-film, cryogenic C-series Pt100/ Pt1000 RTD elements operate down to -196°C, being to cover most “low temperature” cryogenic applications. Approval of Pfizer-BioNTech Covid-19 vaccine has rapidly increased the demand for vessels capable of storing and transporting vaccine at -80°C and below. Heraeus C220 RTDs easily cover this temperature range giving peace of mind in temperature critical applications. If operating in the region of 600°C~900°C, then Heraeus H-series high-temperature elements can sense and regulate your heater, furnace or exhaust gas sensor application. Top of the range HDA420s (Pt200) are capable of operating up to 900°C and intermittently to 950°C. These are typically supplied to the automotive, laboratory and process technology markets.

Variable plastic case according to fire protection class UL 94 V-0 (KSG ...)


Fischer Elektronik is offering its customers the KSG… plastic cases now. It is a universal, light- weight plastic case with a wall thickness of 3 mm. The plastic cases consist of two half-shells which are joined together without screws by snapping the tongue and groove together. The impact-resistant plastic (ABS with fire protection class UL 94 V-0) has a grained surface for an appealing look and a pleasant feel. The customer can choose between three different case colours: tele grey 1 (similar to RAL 7045), graphite black (similar to RAL 9011) and traffic white (similar to RAL 9016). It is also possible to combine different colours for the upper and lower shell. Due to the supplied self-adhesive and non-slip rubber feet, the case stands securely at the installation site. For mounting as a wall case, optional fastening clips are available which are permanently connected to the lower shell.

Cliff DualSLIMS space saving narrow FeedThrough Connectors may be front or back mounted


Cliff Electronics have extended their SLIMS FeedThrough Connector series with the DualSLIMS range which allows customers to choose between mounting the connector adapters from the front of the panel which permits simple and fast changing of connectors in the field, or the rear which brings a lower profile flush appearance to the connectors when rack mounted or side by side. The new DualSLIM connectors now offer panel builders and system integrators the ability to mount up to 20 connectors in a 1U, 19” rack panel. At just 19mm wide the SLIMS range offers a more compact alternative to Cliff’s very popular XLR form factor FeedThrough product range. There are 14 different versions: HDMI, USB3


A-A, USB3 B-A, USB2 B-A, USB2 A-A, USB2 A-B, USB-C F-M, Cat5e, Cat5e Shielded, Cat6, Cat6 Shielded, Cat3, Cat6A Shielded and blank plate. With a total number of 11 variants of each type, the total number of possible variants is 252.

Piezoceramics provide precision and reliability to medical technologies


Piezoceramic materials are commonly used in actuation and sensing applications across a variety of markets and are key to some of the leading-edge


technologies now used in the medical sector. From laboratory diagnostics and microdosing to ultrasonics and even tartar removal from teeth, medical technologies require components that are fast, reliable and energy saving.


Piezoceramics combine these characteristics, giving much higher accuracy and precision – and requiring less power – compared to traditional mechanical actuators and sensors, and are friction free, so are less susceptible to wear and tear, keeping costs down to a minimum. They do not create and are not affected by magnetic fields, and work reliably under extreme conditions, for example under cryogenic temperatures and in vacuums, making them easily adaptable to different environments for such diverse functions as non-destructive testing, therapy and imaging.


Many of the medical applications for piezoceramics deal with controlled flow of liquids in micropipetting applications, taking advantage of the incredible speed and accuracy that they offer down to the micrometre level. Devices are getting more compact as we try to cram more capabilities into the same lab spaces, while the density of sampling is getting higher, creating a need for very small and fast drives for the pipetting process. At the same time, these mechanisms must produce enough force to move the pipettes vertically, but with the accuracy to aspirate or dispense the right amounts. Piezomotors are perfect for this application, as they operate with a tiny footprint as a direct linear drive and can generate high forces. A ceramic that oscillates at ultrasonic frequencies generates a controllable forward motion with uniform speed and unparalleled accuracy. Similarly, piezo


elements in micropumps control and monitor extremely small liquid or gas volumes reliably and precisely in the range of a few hundred millilitres to a few nanolitres. Different types of pumps, such as


membrane or peristaltic hose pumps, are actuated by different drive principles. The piezo elements can be adapted perfectly to each specific application environment, for example miniaturised lab-on-a-chip solutions for mobile analytical


instruments, or microdiaphragm pumps that require compact drives to create continuous and variable flow rates to even the picolitre range. Essentially, any application that needs reliable metering of minute amounts of liquids and gases – from medical uses and biotechnology to chemical analytics and process engineering – can benefit from powerful and versatile piezo technology, and the more it is applied to this sector, the more device manufacturers will realise its potential.
