1. Overview

PR611A/PR613A dry block calibrator is a new generation of portable temperature calibration equipment that integrates advanced technologies such as intelligent dual-zone temperature control, automatic temperature calibration, and precision measurement. It has excellent static and dynamic temperature control characteristics, built-in independent full-function temperature measurement channel and standard measurement channel, and can edit complex calibration tasks. The automatic calibration of thermocouples, thermal resistances, temperature switches, and electrical signal output temperature transmitters can be realized without other peripherals, It’s very suitable for industrial field and laboratory use.

1.2 Technical characteristics

l It adopts dual zone temperature control technology. The bottom and top of the dry block calibrator heating cavity have two independent temperature control, heating and cooling components. The temperature coupling control algorithm is used to avoid the mutual influence between multiple heating zones during the temperature balance process. . The dual-zone temperature controltechnology is the key to ensure that the effective temperature zone remains stable in a complex and changing environment and to improve the axial temperature uniformity.

l Rapid heating and cooling, by matching the heating and cooling capacity of the current working conditions in real time, while optimizing the control characteristics, the heating and cooling speed can be greatly increased.

l Full-featured electrical measurement channel, the full-featured electrical measurement channel is used to measure various types of thermal resistance, thermocouple, temperature transmitter and temperature switch, with a measurement accuracy better than 0.02%. In addition, for better calibration of thermocouple sensors, a dedicated thermocouple compensation socket with a compensation error better than 0.2°C is integrated on the front panel. l For the reference temperature sensor, in order to facilitate the comparison between the standard device and the temperature element to be calibrated, the standard wire-wound platinum resistance is used as the reference sensor, and it supports multi-point interpolation correction algorithm to obtain better temperature traceability accuracy.

l Editable task mode, can edit and design complex task functions including temperature calibration points, stability criterion, sampling method, delay time and other multiple calibration parameters, so as to realize the automatic calibration process of multiple temperature calibration points.

l Fully automatic temperature switch calibration, with a settable slope temperature rise and fall and switch value measurement functions, can perform fully automatic temperature switch calibration tasks through simple parameter settings.

l Supports USB storage devices. The calibration data generated after the calibration task is executed will be saved in the internal memory in the format of a CSV file. The data can be viewed on the dry block calibrator or exported to a USB storage device through the USB interface.
