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.

ERSA IR / PL 650 A third-generation IR rework system offers three new technological innovations: DynamicIR, Multi True Closed Loop Control and IntelligentIRS. Designed to handle rework applications on heavy mass PCBs and large-format SMT assemblies (18 x 20" / 460 x 560 mm) in a lead-free environment.
The safe and proven medium wavelength IR heating technology allows uniform heat distribution from the top and bottom side across the PCB and component. DynamicIR allows fully automatic dynamic control of the top (1400W / 60 x 120 mm) and bottom (3200W / 350 x 450 mm) IR heaters depending on the actual temperature of the component and where it is in the temperature profile. Total available power to the selective reflow system is spread across four separately switchable heating zones on the top and five zones on the bottom. Depending on board size, the thermal mass of the substrate and component size, the required heat energy is delivered at the precise time and location to ensure that component and board follow the prescribed temperature profile. Can run an extended or flat peak, reduces PCB warpage.
True Closed Loop Control means that the actual component temperature is acquired, using the non-contact Infrared sensor, and is used as the primary control mechanism for the heating system. IntelligentIRS allows for precise temperature measurement by choosing from a component table or by component-specific IRS calibration. Either the IRS or a TC sensor of choice can be chosen to drive the heating technology. Multi True Closed Loop Control uses up to four additional TC sensors. By assigning threshold values to these additional sensors, they prevent the fully automatic heating system from undesired overheating of adjacent or bottom side components.
Affords a high level of rework safety by y making it impossible to heat over an assigned threshold value. Thus, it is impossible to work outside a specified lead-free process window.
The system is broken down into four modules: the IR650 Selective Reflow module, the RPC Reflow Process Camera module, the PL650 Precision Placement module and the IRSoft software module.

Transition Automation has a new squeegee holder which is said to improve SMT printing by incorporating a self-cleaning wiper system.
Reduces solder paste sticking by way of two small articulating wiper wires. Results may vary depending on the particular viscosity and rheology of the solder paste. In some cases, users may benefit by altering their solder paste formulations to be more sticky and viscous (which improves printing), without the additional paste sticking worries. The new devices is offered across the full Permalex metal squeegee product line, and may be retrofitted on most popular SMT printing machines.No additional hookups or machine interefacing required, is passively actuated by the motion of the squeegee holder.
