OQ610-S Through Process Data Logging Systems

OQ610-S Through Process Data Logging Systems

The OQ610-S data logger is suitable for taking up to 6 K or T type thermocouple temperature readings for heat treating products in your manufacturing process. The logger is housed in one of the standard, or custom, thermal barriers for protection for the required process temperature and duration. We can supply a wide range of temperature probes for surface, air or insertion measurements to be taken during the process. Standard barriers can handle temperatures of up to 950°C for up to 3 Hrs.

Description

By passing the OQ610-S data logger – protected by a thermal barrier – through your process, a temperature profile can be produced that will show you exactly what is happening to your products and the process. This provides the benefit allowing you to improve the quality of your product, increase efficiency, reduced energy costs, quality assurance reports for compliance and traceability and complete quality control for your process.

Features

  • Complete system for through process monitoring based on 6-channel Squirrel OQ610
  • High accuracy
  • Compact and simple to use
  • USB connectivity for direct print-out of temperature readings with time and date
  • Can be configured to automatically start and stop logging on time or temperature levels
  • Can provide automatic cure calculation in through process applications
  • Wide choice of temperature probes and thermal barriers

 

Applications

  • Food Manufacturing including cakes, bread, confectionery, meat fish, poultry, beverages, dairy products, pizza, pasta, ready made meals as well as chilled and frozen foods
  • Surface Coatings; powder coating & stove enamelling
  • Furnaces, kilns and any form of oven or conveyor system

Thermal Barrier

Thermal barriers are insulated containers designed to keep heat out so that the datalogger inside remains at a safe operation temperature for a specified duration. We offer a wide range of thermal barrier with different time and temperature specifications. A list of standard options are detailed below.

Features

  • Provides protection to Squirrel data loggers when used in high temperature oven profiling applications (static or conveyor)
  • A wide range of standard and customised models with different performance characteristics
  • Made from stainless steel, for years of use
  • Suitable for applications in food, powder coating, stove enamelling, ceramic, kiln and furnace
  • Barriers available for very high temperature applications – manufactured to order
  • Can be constructed using special phase change material for added protection for very high temperature applications.

 

The performance of a thermal barrier is measured in terms of the exposure time at a particular temperature for a given maximum internal temperature. The performance is closely related to the barrier’s insulation thickness. The table below indicates the allowable exposure time (in minutes) of temperatures for the standard (thermal barrier models assuming a maximum internal temperature of 70°C).
