New test and simulation products increase efficiency and productivity

Pickering Interfaces has a new high-accuracy PXI RTD simulator. The device is a cost-effective method of simulating PT100, PT500 or PT1000 RTDs from -150C to >850C. The unit supports 4, 8, 12, 16, 20 or 24 channels in one or two PXI slots. Additionally, channels may be set as short- or open-circuit to simulate faulty wiring to a sensor. The module is available with the following resistance ranges: 40Ohm to 900Ohm for PT100 simulation; 200Ohm to 4500Ohm for PT500 simulation; and 400Ohm to 9000Ohm for PT1000 simulation. Control is simple, using resistance calls. New PXI and PCI high-density precision programmable resistor modules offer a simple solution for applications demanding accurate simulation of resistive sensors. Units are offered in a mixture of resistance ranges from 2Ohm to 22MOhm and with resolutions to 0.125Ohm (±0.2%) to meet the requirements of functional test systems. Applications include engine controller testing where resistive sensors give information such as temperature. The modules’ channels can be set as short or open-circuit to simulate a wiring or sensor fault. Software control is made easier by the use of resistor value calls. The module decides the channel setting closest to the requested value and sets that value. The user can interrogate the module to find the actual resistance setting used by the module The company's new 60-106 six-slot modular USB/LXI chassis provides a small 1U rack-height form factor, making it perfect for space-restricted rack-mount applications. The chassis supports between one and six of the company's 3U PXI Switch and Simulation modules; possible systems include switching matrices up to 3312 crosspoints or up to 108 channels of programmable resistor/sensor emulation.
