Thayer Scale instrument product range

Thayer Scale Instrument Up-grades for Competitor’s Belt Scales

S5200 – enhanced instrument (integrator or controller) with extra I/O and analog outputs and front-end digitizing at scale with Scale Unit. Data is transmitted via RS485. S5200 is used on all NTEP and high accuracy (0.1 – 0.25%) belt scales.

S52i or S52c – simplified instrument (integrator or controller) with similar screen as S5200 but with limited I/O and analog functionality. No front-end digitizing of load and speed.

i340 – simple integrator with I/O, analog capability. No front-end digitizing. Ethernet IP/Modbus TCP only

All instruments have Ethernet IP/Modbus TCP and Profibus communications except i340.

Conversion modules are available for Profinet communication links where needed.

Available options

  • Type 4 painted carbon steel enclosures
  • Type 4X 304 or 316 stainless steel enclosures.
  • I340 available in Type 4, 4X and 4X non-metallic.
  • S5200 and S52 are available for use in classified area. i340 is not for use in a hazardous location. S5200 can be up to 4000’ wire feet from a scale.
  • S52 and i340 can be up to 1000’ wire feet from a scale.

Instrument integrator parts

  • Summing junction in Type 4X stainless steel enclosure for any belt scale with more than one load cell.
  • Single channel pulser input board for mating with Thermo belt travel encoder/pulser; 60-12C.
  • If speed is extremely slow and the competitor’s speed encoder is unusable, Thayer Scale will provide Belt Travel Pulser Assembly (photos below) with high resolution encoder/pulser, or the same device with a mounting kit for installation on a bend or tail pulley.

Test weight lifter and storage

weight-lifter

The test weight lift and storage assembly provides a safe, convenient method of placing the calibration weight on the scale weigh bridge accurately and provides these advantages.

  • SAFE – Eliminates need to go between belt strands
  • EASY – Permits one person to operate
  • CONVENIENT STORAGE – Prevents loss or damage
  • REPEATABILITY – Weight is always positioned in the same location test after test

Belt Travel Pulser

belt-tension
  • Digital Pulse Output
  • Heavy-duty Construction
  • Spring loaded to maintain positive tracking
  • Self-cleaning
  • Minimum surface area for material build-up
  • Easy to install
  • Unaffected by temperature and voltage variations

Precision Belt Speed Measurement

Accurate belt speed measurement requires the use of a precision wheel and pulser. A spring is used to maintain proper contact pressure of the wheel with the tension side of the belt in all operating conditions. The Thayer Scale belt travel pulser assembly includes a precision cast/machined wheel with a ‘pre-calibrated’ circumferential tolerance of ± 0.05% and a high resolution digital transmitter. the transmitter produces pulses equivalent to 1/100 to 1/200 of a foot of belt travel. The speed pick-up wheel has a narrow face width so it’s less susceptible to material build-up, which can result in speed measuring errors. since belt stretch is not constant throughout the length of the conveyor, and therefore, can affect speed measurement, the speed pick-up produces a more accurate speed signal than that which is produced by tail pulley mounted speed encoders.
