The purchaser will be asked which equipment they wish to have maintained and or calibrated. Once a quote is generated, the purchaser will issue a purchase order to Leming Process Services LLC for quoted amount. When the service visit is completed, a final value will be calculated to allow the purchaser to update their PO amount. 

Leming Process Services LLC is not authorized to travel until we have obtained a copy of the PO. 

Alternatively, a credit card can be used to schedule directly from this website. A 3% surcharge is added to invoices paid via credit card.

• What tolerances are used when calibrating a feeder?
  • LPS will typically use the customer's tolerance. Every process is different. Some require within 5% while others are 0.5% or even less. Static weight checks should be less than 0.1% error while material catch samples are 1-0.5% or less. 

• Can you calibrate the feeders scale in our facility? 
  • Yes. LPS has certified, calibrated weights traceable to NIST standards. Depending on the feeder type, Class 6 or Class 7 weights will be used. All weight calibration certificates are available for your records. It is LPS policy to only use the weights for calibration within 1 year from their last calibration date.

• How long will your visit last?
  • When there are multiple feeders on one line, we can finish one feeder completely in one hour. This would include a mechanical check, speed check, static weight check, and a catch sample check if desired. Average time per group of feeders is 1 - 1.5 hours / feeder. 

• Which controllers and feeder types will you calibrate?
  • LPS can calibrate any Coperion K-Tron  ™   controller or feeder if it has a digital interface. All scales can be certified. The B3-B4 scales may not be repairable. K-10s, KSM, SCM, and KCM controllers are all able to be calibrated by LPS.
