KEITHLEY 7402 Thermocouple Scanner Card

The Keithley 7402 Nine Channel Thermocouple Scanner Card permits monitoring of up to nine thermocouples or other transducers. The nine signal channels use a guarded 2-pole configuration. An isothermal block provides electrical isolation up to 42 V while assuring excellent thermal conductivity between cold junction terminations. A sensing device mounted in the isothermal block monitors the cold junction and outputs a calibrated reference voltage that is linearly related to the temperature. Specifications. Number of Channels: 9. Card Configuration: Multiplexer. Contact Configuration: 2 form A. Maximum Voltage: 110 V. Maximum Current: 1 A. Maximum Power: 60 VA. Contact Potential: <1 uV. Contact Life: >10^8 closures cold switching; >10^6 closures at maximum signal levels. Connection Type: Screw terminal. Temperature Offset: ±0.05° C maximum from HI to LO of any channel or between any two adjacent channels in one column on the isothermal block. ±0.1° C maximum between any two terminals on the isothermal block. Maximum additional dynamic offset due to 10°C step change in environment: ±0.1°C after one hour settling. Reference Output: +200 uV/C (+54.63 mV at 0°C).

*This is a Web introductory price for one calibration of the KEITHLEY 7402. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Average Power
Average power means that the energy transfer rate is to be averaged over many periods of the lowest frequency involved. For a CW signal, the lowest frequency and highest frequency are the same, so average power and power are the same. For an amplitude modulated wave, the power must be averaged over many periods of the modulation component of the signal as well.

Dynamic range
Dynamic range the ratio of a specified maximum level of a parameter, such as power, current, voltage or frequency, to the minimum detectable value of that parameter.

Modulation
Modulation is the process by which the characteristic of one wave (the carrier) is modified by another.

Repeatability
Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.
