Current Transformers
In the field of control systems the current transformers are applied to facilitate higher currents in areas of process technology. Current transformers are in terms of their working mechanism similar to current clamps. A current transformer draws the current inductively through a winding and supplies it for measuring instruments. Thus current transformers enable measuring high currents, while isolating the measuring instrument from potentially higher currents. By that the safety is improved and a continuous monitoring of machines is supported. The current transformers measure a few amperes as well as a couple of 1000 Ampere per phase. Current transformers are applied for the measurem
ent of alternating currents. Typically the current transformers are equipped with a 1 A or 5 A output. Specially constructed current transformers have a  4 20 mA output. Thus the measured current can be directly indicated on a process indicator or logic modules. A special group of current transformers are the current transformers for direct current. With these current transformers the current is determined through Hall effect sensors. An electronic device, that is mounted at the downstream side and thus facilitates direct current for process technology. If you can't find the current transformers you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: UK customers +44(0) 23 809 870 30 / US customers (561) 320-9162 and our technical staff will advise you regarding our measuring instruments. Our engineers and technicians will be happy to help you with the diamond testers, and of course, with the other products in the field of regulation and control, and scales and balances.

Furthermore current transformers are not only designed for measuring currents. Current transformers are of great importance in areas of control systems since they convert the measured variables into electrical signals. Thus the physical measurands for another part in the measuring chain can be determined. The most common current transformers are those that measure temperature and the rotational speed. But current transformers for gas, sound and light are more and more in demand. The current transformers that convert those measurands, in fact convert those into electrical standard signals. These standards signals can be 0 20 mA, 4 20 mA or 0 10 V. These standard signals are expedient since by coming from the current transformer they can be sent over a larger distance. The 4 20 mA standard signal provides furthermore the advantage that in case of an apparently lower current than 4 mA provided by the current transformer, the operator will immediately  know that something is not right. The output signals are preset by the manufacturer. Some current transformers offer the option to change the output signal by remounting jumpers or by reprogramming on the computer. Additionally to the analogue outputs, some current transformers are feature displays and alarm outputs that facilitate operating the current transformer significantly. The inputs and outputs of the signal transformer are electrically isolated meaning that no electrical signal at the input is in direct contact with the output.
