ADM are experts in the field of refrigeration and temperature control. Whether you need a simple to use standalone controller, or one that has a high level of functionality that can be integrated into a higher-level control system, ADM can help. In fact, in most cases we can offer a temperature or refrigeration controller from stock! ADM represents Eurotherm and Elco in Australia. Advanced Temperature Control from Eurotherm Eurotherm was founded in the UK in 1965. From the outset they have designed and manufactured temperature controllers, so it is fair to say that Eurotherm are the world’s

There are several types of linear position sensor available, many of which are stocked by ADM. One question we are frequently asked is what is the best type of linear position to use? The answer is it very much depends on your application. Where some people can be confused is determining the difference between linear potentiometers and LVDT transducers. What are the Differences Between LVDTs and Linear Potentiometers? Linear Potentiometers and LVDTs (linear variable differential transformers) have several features in common, which makes it a little unclear as to which applications each is best

ADM stocks the TSA range of mechanical pressure switches. This new range of pressure switches is manufactured in the USA and has a proven track record for reliability and quality. There are two series in stock: TSA-APA: For low pressure applications. 0.3 – 2.1bar measuring range 3.5 – 10bar measuring range TSA-BPA: For high pressure applications. 8.6 – 41bar measuring range 35 – 172bar measuring range 69 – 414bar measuring range Other measuring ranges are available via special order, with the lead time being approximately 4 weeks. The TSA pressure switches can be custom set to switch at a

Industrial load cells incorporate an internal strain gauge sensor that when provided with an excitation voltage, will output a mV/V signal that is directly proportional to the weight being applied to the load cell. This mV/V signal is not a type that is commonly used with industrial displays, PLCs or remote I/O modules. Also, the mV/V signal is not conducive to being transmitted over distances longer than 10m, without signal degradation or interference becoming a significant factor. Therefore, conversion to another standard signal type such as a 4-20mA analogue electrical output is often

Vibration monitoring is a tried and tested method of monitoring the condition of critical machinery and plant, so that preventative measures can be taken to avoid costly breakdowns and unnecessary maintenance runs. What is Vibration? A body is said to vibrate when it describes an oscillating motion about a reference position. Velocity and acceleration are the 2 attributes that are most closely associated with vibration. If we assume that the oscillating motion of vibration is sinusoidal, then there are only 3 questions you need answers to in order to select an accelerometer: What is the

Many industrial and process control applications involve the monitoring of the level of a liquid in a vessel, or storage tank. There are several methods that you could use to measure or monitor liquid levels. Not all measurement methods are suitable for every application, each has its own pros and cons. Ultrasonic Liquid Level Measurement A non-invasive solution often used for measuring level in applications where media remains untouched for corrosive media or hygienic needs, ultrasonic sound reflecting technology is utilised for top access applications. Pulsar Measurement has pioneered

As a distributor of Harting connectors, ADM Instrument Engineering stocks a considered range of industrial connectors. On top of that we have access to the full range of Harting industrial connectors. Harting manufacture several different types of industrial connector and this blog post has been written to give you a good idea as to what Harting’s capabilities are. Harting HAN Industrial Connectors Harting HAN connectors are very popular with designers, manufacturers, and installers of industrial equipment. This type of industrial connector has a modular design, which allows you to configure

When selecting a linear displacement sensor, you often find two different technologies are under consideration: String Potentiometers (string pots) Draw Wire Encoders The mechanical design principles of both are similar, with the main deciding factors being travel length and robustness. However, when it comes to the electronics there are many different options to choose from. As well as a broad variety of rotary encoders being available, you also have what is essentially a multiturn potentiometer with some additional signal conditioning electronics. There are some fundamental differences

There are two main groups of pressure switches that are designed very differently and best fit very various applications. These are either Mechanical and Electronic pressure switches. Here’s how pressure switch work and where best to use each one. How Mechanical Pressure Switches Work Directly behind the pressure switch’s process connection port is a either diaphragm, piston, or bellows chamber. The medium’s pressure deforms or moves against an end stop and the chamber acts directly onto a micro switch, or potential free contact. The setpoint can be adjusted by an adjustment screw or Allen key

The IEC (International Electrotechnical Commission) classifies hazardous areas into various Zones. Explosive Gases Zone Definition Zone 0 An area in which an explosive atmosphere is present continuously for long periods of time or will frequently occur. Zone 1 An area in which an explosive atmosphere is likely to occur occasionally in normal operation. It may exist because of repair, maintenance operations, or leakage. Zone 2 A place in which an explosive atmosphere is not likely to occur in normal operation but, if it does occur, will persist for a short period only. These areas only become
