National Instruments CAL-4353 Calibration Terminal Block

The CAL-4353 (Part Number: 781350-01) Front-Mounting Calibration Accessory by National Instruments is an essential tool designed to facilitate precise calibration of the PXIe-4353 32-Channel, 24-Bit PXI Temperature Input Module. This accessory ensures accurate temperature measurements by providing a means to calibrate and verify the performance of the input module.

Because of its intuitive design, the CAL-4353 makes it simple to front-mount, which streamlines the calibration procedure. It provides versatility in calibration methods by being compatible with both 2-wire voltage calibrators and 4-wire resistance calibrators. This accessory has several safety features to guard against malfunctions. The inputs are safeguarded against ±30 VDC to ground and between TC+ and TC–, thereby reducing the possibility of damage during calibration processes.

It is recommended that the CAL-4353 be calibrated on a yearly basis, or more frequently, in order to preserve peak performance. Furthermore, in order to guarantee consistent and accurate results, it is recommended to allow 15 minutes for warm-up prior to beginning calibration processes.

The CAL-4353's compact size and weight of 525 g make it easy to handle and include into calibration setups. Its measurements are 15.28 x 12.95 cm (6.02 × 5.10 in.).

The device is intended to function in an ambient temperature range of 0°C to 55°C and can tolerate non-condensing relative humidity values of 0% to 90%. It is feasible to store food at temperatures between -40°C and 71°C and non-condensing relative humidity levels between 5% and 95%.

The CAL-4353 is designed to fulfill MIL-PRF-28800F Class 2 standards, withstanding shocks up to 30 g peak, half-sine, and 11 ms pulse throughout operation. In order to provide dependability in demanding situations, it also withstands random vibrations in both working and non-operating phases.
