Description

LR-Cal LTC-DB-0550-60 description

The LR-Cal LTC-DB-0550-60 metal block temperature calibrator with a particularly large immersion depth serves as both a temperature source and a reference device for testing and calibrating all types of temperature measuring instruments.

Temperature range from ambient temperature to +550°C
Ramp function
Thermostat tests
Computer-controlled calibrations via computer interface (PC software optionally available)
Various metal block inserts with different bores for test specimens available
Due to the large immersion depth, the holes are designed as milled recesses (around the circumference). When the insert is inserted, this results in the desired holes
Includes factory certificate of accuracy, stability, and performance
Computer interface (RS232, RS232-USB interface converter available as an accessory)

Note: This calibrator does NOT include a block insert in the standard scope of delivery.

Explanations regarding metal dry block temperature calibrators

The test object (all types of temperature measuring devices, e.g., dial thermometers, resistance thermometers, temperature switches, thermostats, etc.) and the reference temperature measuring device (built into the calibrator or external reference) are subjected to the same test temperatures. The measured values of the reference are compared with the values of the test item. This allows conclusions to be drawn not only about the function of the test item, but also about its measuring accuracy and measured value deviation.

Please note that the information specified in the respective technical data regarding radial and axial temperature uniformity refers to specific immersion depths and may not apply to all immersion depths in every case. The temperature range specifications apply at an ambient temperature of +20°C.

The LR-Cal metal dry block temperature calibrators have an internal (built-in) reference. If its accuracy is insufficient, an external reference (with or without its own display) can be used.

The -2I version provides 2 measurement inputs, for resistance thermometers or thermocouples. Here, you can connect, for example, a test object and an external reference sensor, or 2 test objects and a temperature transmitter. The values of these connected sensors are shown on the calibrator's display.

Furthermore, the LR-Cal Aq2Sp2 PC software is available as an accessory for the LR-Cal metal block temperature calibrators. This software can be used to control the calibrator via its RS232 interface (optional with USB converter), perform manual or automatic calibration of one or more test objects, load and endurance tests, thermostat tests, and create calibration certificates.
