Heading in to 2021...

Looking forward to 2021 !

Well, what can we say about 2020 that hasn’t already been said?! It was a strange year with many unexpected twist and turns. We have been delighted to be able to continue supporting our customers with the same high quality products and service throughout it all. We’re grateful to all of our employees for adhering to our changes in safety measures, enabling us to remain largely unscathed by the Covid-19 crisis.

Looking forward in to 2021, we have lots of exciting plans. Here’s a few things that you can expect from us this year;

New Products

Our most exciting new product this year will be the new range of RS485 Serial Interface pressure transmitters. We will be releasing general purpose, high pressure and submersible versions, with a selection of electrical and process connections, to create a range that covers a whole host of applications. The transmitters have direct digital output on RS485 bus, which makes them ideal for use in modern industrial communication systems. When the finishing touches to the range are complete, we’ll let you know!

Online training sessions with our sales partner network

Our network of sales partners is getting bigger, as we form new relationships with companies around the world who share our commitment to provide high quality pressure measurement solutions. We aim to have regular online product and service training sessions throughout the coming months so that no matter where you are in the world, there will be a sales partner close by who can assist you with our product range.


Check out the events page on our website to find out which exhibitions we’re signed up for this year. All events are relying on the demise of the pandemic of course, so we’re keeping our fingers crossed.

We are particularly looking forward to Ocean Business which takes place from 6th July at the National Oceanography Centre in Southampton (UK). It will be our first year exhibiting at this exciting show and will be the perfect opportunity to showcase our range of DNV GL certified pressure transmitters, developed especially for the Marine industry.
