FrameScan FX is an advanced vectorless test tool for detecting open pins on components and connectors assembled onto PCBs. Uses an enhanced in-circuit capacitive coupling technique that tests for open pins by applying an AC signal to an un-powered PCB node and measuring the voltage coupled to a plate positioned in close proximity to the component or connector being tested. Users can reportedly detect open pins more accurately and with greater repeatability.
The complete hardware and software suite can extend measurement capabilities. Solves test issues associated with smaller device packages and connector technologies. Hardware improvements include a new low-noise op amp that increases the front-end gain of the active probe to minimize the effects of noise upon other stages of the measurement circuit. Software improvements include an automatic Precision Mode that increases the number of measurement samples for low measurement signals.

Panel-mount pressure sensors, such as Model AST4200, were designed to provide a hermetic seal against the media without the use of adapters. The one-piece bulkhead design mounts through the panel to keep hazardous media out of the control box. The solid one-piece 17-4PH or 316L high strength stainless steel design is free of welds, internal O-rings or fluid-filled cavities. Requires a minimal mounting configuration that uses a standard panel punch. A locknut holds the sensor to the panel and leaves room for a gasket. Two wrench flats on the nose of the sensor allow the user to tighten the external pressure tubing to the sensor without turning the part.
Units offer outputs of 10mV/V, 4-20 mA or 1-5V. Said to provide long life and resistance to media corrosion as well as over range and burst protection. Offers wetted material such as titanium and nickel alloys to produce strain gauge sensors that yield a high output with low thermal errors.
Provide gauge, sealed gauge or compound gauge pressure measurement in ranges up to 10,000 PSI. Sensors are calibrated and temperature compensated to ensure stability over specified ranges. Units offer accuracy of < +0.5% BFSL at 25ºC (77º F) and long-term stability of +0.25% full-scale output per annum. Exhibiting resistance to high vibration, shock and temperature extremes, and high levels of EMI/RFI filtrations, units perform in demanding environments.
