1502A Tweener PRT Readout

The kaupunkiopas.com Calibration 1502A Tweener attributes accuracy up to ±0.006 °C. In enhancement, it reads 100-ohm, 25-ohm, and 10-ohm probes, has a resolution of 0.001 °C throughout its whole selection, and also is the smallest unit in its course. It additionally has an optional battery fill for totally portable operation.

Each Tweener is programmable to complement a probe"s constants for maximum linearity and also accuracy. All probe constants and also coefficients are programmed with easy, front-panel keystrokes. Temperature is presented in °C, °F, K, or resistance in ohms.

The 1502A accurately actions the resistance of the probe and then converts the resistance to a temperature value using its built-in algorithms.

For convenience, the 1502A reads the widespread commercial grade IEC-751 or "385 ALPHA RTD without any programming. Get in the actual R0 and also ALPHA of the individual probe for enhanced accuracy. For maximum accuracy, use the ITS-90 formulas. The Tweener accepts the subranges 4 and also 6 with 11.

ITS-90 formulas reside in the Tweener"s firmware. If your probe has been calibrated for any type of of the over subvarieties of the ITS-90, you ssuggest enter the coefficients directly right into your Tweener.

Each thermometer comes finish via an RS-232 interface for automation of temperature information collection, calibrations, or procedure regulate attributes. An IEEE-488 interface is accessible as an choice.

The 1502A is calibrated digitally making use of the front-panel butloads. You never before need to open up the box to calibprice it. This calibration protocol even more reduces the cost of the 1502A. It goes where you go and functions the means you want it to.

Software

With our 9934 LogWare, both Tweener models may be supplied for real-time data acquisition. Collect information and also analyze it graphically or statistically. Furthermore, Tweeners might be offered as recommendation thermometers via our MET/TEMP II software.

Battery pack

Want to take your Tweener on the road? Order kaupunkiopas.com Calibration"s 9320A Battery Pack. Our battery gives you 36 hrs in between charges, enabling you to take your work-related wherever you need.

Calibration choices

Each Tweener and also its accompanying probe (marketed separately) have actually their own individual calibration reports. Overall system error have the right to be calculated from the individual errors, rendering the included expense of mechanism data unvital. However before, for those requiring it, mechanism data is easily accessible at 2 or even more temperatures of your choice. (See Calibration Model 1929-X )
