Turn key setup of The DSE moisture measuring system

Crane with moisture meters for SleafordSleaford Renewable Energy plant is a sizeable biomass-fired power plant in North Lincolnshire, England. The biomass is preferably straw, typically supplied by local straw vendors. 

As the main contractor for the straw handling system, C&H System chose DSE to supplier the well-known DSE4100 moisture meters for cranes. 

To take advantage of DSE’s experience in moisture testing, C&H System asked DSE to make a turnkey setup of the moisture measuring system, offering the sensors and installation on the yokes and onsite run-in and verification.

Having a moisture division at DSE with a full workshop of dedicated mechanical and electrical fitters and assigning a team to do the installations and verifications was easy.
