Measurement solutions experts

Due to our unique variety of sensors and measurement components, Berthold offers the optimal solution for measurement performance, feasibility, and cost. With hundreds of systems installed in pulp & paper mills across the world, we have the experience and the technical know-how to solve your measurement task, regardless of it if is a new system or a retrofit is required.

State of the art technology

  • Experts in retrofitting with current sources
  • No exposure to process media and therefore unaffected by acidic, caustic, abrasive and sticky condition
  • Noncontact, therefore no wear and tear
  • Easy to install on existing pipes and vessels with clamp-on devices
  • Smooth handling and operation
  • Outstanding longterm stability

Retrofit solution

With hundreds of systems installed in pulp & paper mills throughout the world, we have the experience and the technical know-how to solve your measurement task. Nuclear measurement sources naturally decay over time, losing their strength, until eventually there is not enough activity left to reliably measure your process with the current detector. Source replacement is costly, time consuming, and does not work towards a reduction in overall site source activity. Fortunately, we have another solution. Instead of replacing the source, you might be able to replace the electronics and continue using your existing source. Berthold has the most sensitive and stable detectors on the market, a simple electronic replacement allows users to extend the life of their existing sources by years, while improving measurement reliability for all density and level applications.

Detector retrofit program to improve your production

Especially in low radiation conditions, our highly sensitive detectors improve the signal to noise ratio, resulting in superior performance when compared to competing system. Replacing your existing detector with a more sensitive Berthold detector will delay source replacement, which is costly, time consuming what is resulting in superior measurement performance compared to competing systems. Source replacement is costly, time consuming, and does not work towards a reduction in overall site source activity.

Berthold's retrofit solution

SIL certification available

The SENSseries LB 480 detectors are certified for use in SIL2 applications. Even SIL3 is achieved with homogenous redundancy. The certificate covers all measurement applications, from high level or low level alarms to continuous level measurement. Thus safe operation of critical pulp and paper processes is guaranteed.

Long-term stability

A reliable measurement, requiring no recalibration, is vital for the operation of the alky unit, and is our highest priority. Berthold’s detectors offer stability in the face of changes in ambient temperature. Even drastic temperature shifts, e.g. from winter to summer do not cause measurement drift. Our patented method for detector stabilization compensates for temperature changes and aging.

Detector Stability

Minimal source activity

We are committed to the ALARA principle. ALARA stands for: As Low As Reasonably Achievable, and aims to keep the source size to a minimum. According to this, our sources are specifically sized for your individual application. As a result, our sources are equipped with remarkably low activities, due to our highly sensitive detectors.
