DIN Signal transmitters for load cell, process, pulse and temperature
High precision signal transmitters which are PC-programmable and only 22.5mm wide. We can also supply them pre-configured for you, so you only need to connect.
They are ideal for use in most industrial measurements, catering for 4 or 6 wire load cells, 4-20mA and 0-10V process signals, DC voltages up to 600V and DC current up to 5A.
New: Ex nR Atex Certified build options available
For hazardous areas we can offer the following explosion proof options on most models. Tell us what you need and we will be pleased to quote for Atex certified systems
The London Electronics ATEX certified products are supplied certified for use in the condition in which they are supplied. No liability will be assumed for any loss or damages of any nature, direct or indirect, including any loss of profits or consequential damages, injury or death suffered or incurred by the buyer as a consequence of failure to install, use and/or apply the product within the scope of the installation document and certification supplied.
They also include pulse input versions for total, rate, period, phase angle and quadrature.

Programming the transmitters
We offer free setup software for use on Windows PCs. You will need a cable from your PC to the RS232 port of the transmitter.
Triple 4-20mA loop splitter - TIM018-Mk2
Improve the security of your distributed 4-20mA loops. Designed and built by us in the UK. The TIM018-Mk2 takes one 4-20mA input and splits it 3 ways. Each output loop can be scaled separately.
Self powered 4-20 mA loop isolator P17G
The P17G is a compact, high precision loop isolator, made in Poland, which does not need an external supply. It takes its power from the 4-20mA input signal.
