Depew, NY, USA – PCB Piezotronics (PCB®) has introduced a new dynamic pressure sensor, ideal for measuring dynamic combustion pressure in gasoline or diesel engines. The high temperature (to +600 °F/+315 °C) piezoelectric charge output sensor, structured with naturally stable quartz sensing elements, is well-suited to measure rapidly-changing pressure fluctuations over a wide amplitude and frequency range. The un-cooled design measures pressure with low thermal shock error, and ground isolation avoids electrical interference from electronic ignition systems, making the sensor equally well-suited for research and development or monitoring applications. A solid-state construction, hermetically-sealed housing, and laser-welded flush diaphragm help ensure durability in harsh engine testing environments. The Model 175A01 pressure sensor is available with a dynamic range to 4000 psi (275 bar), and sensitivity of 1.5 pC/psi (21 pC/bar). Alternate models and mounting adaptors are available for various engine types. ...

Depew, NY, USA – The Series 684 indicator alarm module from the IMI Sensors division of PCB Piezotronics provides an economical solution to machine shutdown protection when increased vibration levels signify potential failure. These modules are available in various sizes and include up to eight channels in a single NEMA 4X enclosure. ICP® (IEPE) piezoelectric or 4-20 mA sensors interface directly with the system, which is universally powered and provides appropriate excitation voltages. Within each indicator channel is up to four form C relays, for alarm and shutdown control. Time delays and push button programmable settings allow for simple set-up with no false alarms. Indicator lights on the front of each unit display relay status. Each meter has the ability to integrate an acceleration signal and display the units in acceleration, velocity, or displacement on the highly visible, bright display. The raw vibration signal can be accessed via BNC connections on the front of the module for easy interface with data collection equipment. Also available is the capability to retransmit a signal for straightforward interface with existing PLC, DCS, and SCADA systems. Series 684A vibration alarm modules also conform to applicable European Directives for CE marking. ...

The new Low Cost Shear Beam will save you up to 70% of standard cells. On the basis that the serious OEM scale makers do not want glossy brochures, expensive individual packaging or non basic additions we have launched a quality range of load cell Value Packs. The LCSB is available from 500Kg to 5000Kg. Value Packs have some specific differences to our standard offering. The first thing is that they can only be obtained via Internet orders placed directly from you the customer, they are not available outside our on-line services. They are supplied in set quantity packs, usually in packs of 4, 8, and 12 or more, they are only sold in the quantity packs seen on our on-line services. We have trimmed all the non-essential fat off these load cells, however you can be sure that nothing has been trimmed from the actual load cells, they are precision tested and certified to meet all the exacting requirements on the downloadable technical specifications form our web site. Each load cell comes with the standard PT Ltd serial numbered accuracy certificate and our famous 3 year warranty. ...

Continuous Bearing Temperature & Belt Misalignment Monitoring System. The new HotBus™ Digital Serial Communication System from 4B offers customers a much simpler and more cost effective approach to continuous bearing temperature monitoring. With up to 256 bearing sensors on a single twisted pair cable, installation is much easier and maintenance free. The system allows complete control with user adjustable relative ambient and absolute trip points for each sensor. HotBus Control Units can be stand alone or connected to relay control units to provide automatic machine shutdown. Ethernet, Modbus, and Device Net Gateways are also available for connection to existing networks. Software is provided for system test, system status and uploading of meaningful sensor names and logging / trending bearing temperatures and alarms. The HotBus system can also accept TouchSwitch and other switched contact inputs on the same network. Features: - Max Sensors: 256 sensors on one twisted pair Network - High Speed: 4 second scan time on 256-sensor network - Versatile: Connect up to 8 relay control units (64 relays) - Approvals: ATEX and CE. ...
