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.

Clipping
Clipping is the limiting of a signal so that it never exceeds some threshold.

Line Regulation
Line regulation is the capability to maintain a constant output voltage level on the output channel of a power supply despite changes to the input voltage level.

Peak Envelope Power
Peak envelope power is the maximum value of the envelope power. Envelope power is measured by making the averaging time much less than 1/fm where fm is the maximum frequency component of the modulation waveform. The averaging time is therefore limited on both ends: (1) it must be small compared to the period of the highest modulation frequency, and (2) it must be large enough to be many RF cycles long.

RMS
RMS or root mean square is a statistical measure of the magnitude of a varying quantity
