PXI Millivolt Thermocouple Simulators
Series 41-760
Simulator
This series of PXI Thermocouple Simulator Modules is available in a choice of 32, 24, 16 or 8 channelseach channel providing a low-voltage output across two connector pins capable of providing 20mV with 0.7V resolution, 50mV with 1.7V resolution and 100mV with 3.3V resolution, covering most thermocouple types. These thermocouple simulators use two wire outputs with a remote output reference sense to ensure the modules deliver accurate low-level voltages, even if the system has common mode voltages present. In addition, each simulation channel is also able to provide an open circuit setting to simulate faulty wiring connections to a sensor.

Instrumentation Amplifiers
-
Analog Devices instrumentation amplifiers (in-amps) are precision gain blocks that have a differential input and an output that may be differential or single-ended with respect to a reference terminal. These devices amplify the difference between two input signal voltages while rejecting any signals that are common to both inputs. The in-amps are widely used in many industrial, measurement, data acquisition, and medical applications where dc precision and gain accuracy must be maintained within a noisy environment, and where large common-mode signals (usually at the ac power line frequency) are present.

Sound Level Calibrator
511E
-
Accepted internationally 1 kHz represents the "0 dB" reference point of A, B, C Weighting and other filters utilized in acoustic measurement. The Pistonphone - a mechanical sound source - offers a slightly higher degree of accuracy at a substantial increase in cost. In addition, the 200 or 250 Hz operating frequency is mechanically limited and not suited for measurements of filtered inputs. The 0.2 dB accuracy is quickly lost in the 0.7 to 1.5 dB tolerances acceptable for weighting filters at frequencies around 250 Hz.

Counters, Timers, And Ratemeters
-
ORTEC offers the broadest range of nuclear counters, timers, rate meters and multichannel scalers. Counters simply count the number of input pulses received during the counting period. Timers count pulses generated by an internal or external clock and are used to measure elapsed time, or to establish the length of the counting period. Rate meters provide a readout of the pulse count rate. Multichannel scalers count the number of events that occur during a specified time interval, referred to as the dwell time, resulting in a time-histogram of counts. “Standalone” and programmable computer controlled versions are available.
