High Frequency ICP® Industrial Accelerometer Operates to 30k Hz for Gear Mesh and Bearing Fault Diagnosis


Depew, NY, USA – Model 621B40 high-frequency industrial ICP® accelerometer from the IMI Sensors division of PCB Piezotronics (PCB®) works with online or portable monitoring systems to provide reliable, effective vibration monitoring. It operates to 30k Hz, even with a magnet, and captures high frequency gear mesh faults often missed during routine route-based measurements. Due to the sensor’s high frequency range, it is ideal for measurements on high-speed compressors, gear boxes and turbomachinery, for early detection of impending problems.


When analyzing the condition of an integral gear compressor, a technician must be able to examine gear mesh frequency and its sidebands. The harmonics of the gear mesh and natural frequency of the gears play a significant role in diagnosing potential machinery faults.  A magnetically mounted Model 621B40 supplies a response to more than 30k Hz, allowing a vibration analyst to obtain precise measurements of these high frequency phenomena ...

AST Announces ANSI/ISA 12.27.01-2003 Single Seal Compliance for Explosion-Proof Pressure Sensor Series


Mt. Olive, NJ – American Sensor Technologies, Inc announces its compliance to ANSI/ISA 12.27.01-2003 for their AST4600 Explosion proof Pressure Transmitter. ANSI/ISA - 12.27.01-2003 “provides specific requirements for process sealing between electrical systems and flammable or combustible process fluids where a failure could allow the migration of process fluids directly into the electrical system. Examples of this type of seal include diaphragm seals, thermowells, and pump seals.”


Tested by the Canadian Standards Association (CSA), all AST4600 pressure sensors will now be engraved with the Single Seal marking to indicate compliance.  The housing will include the ambient (-40° to 85°C) and process (-40° to 125°C) temperature range information, along with the CSA 30 Class 1 Division 1 Explosion proof [Groups A, B, C, D] approval marking.  A single seal pressure sensor has a significant cost savings and is much more compact than dual seal devices.  AST4600s offer the added benefit of Krystal Bondä Technology, allowing pressure measurement through a solid piece of stainless steel [no welds, oil-filled cavities, or internal O-rings] ...

Miniature Load Cells


FUTEK Advanced Sensor Technology, Inc has expanded its Load Button Load Cell product line by adding the new miniature model: Miniature Load Button LLB130.  The Miniature Load Button LLB130 is offered in 5, 10, 25, and 50 lbs capacity range with an outside diameter of 0.38” and an incredible height of 0.13”, which has now made the LLB130 the smallest load button load cell offered by FUTEK. The new model also offers several advantages besides its miniature size such as its high quality, accuracy, and internal compensation. The internal compensation offers a great benefit to customers who need to cut the cable since it won’t affect the temperature compensation or zero balance of the unit. FUTEK engineering lab has also utilized a custom proprietary strain gage for this model, ensuring that the highest quality requirements are met ...

New IMPACT Series Fluid-Free Pressure Transmitters


Telford UK – January 2008: Gefran’s new IMPACT series fluid-free pressure transmitters are designed for use in high temperature environments of up to 350°C for applications such as melt pressure feedback on plastic extruders used in food and medical industries. With no mercury or oil filling, the RohS compliant range uses latest MEMS technology to produce a silicon on insulator (SOI) sensing element that allows a process contact membrane of up to 15 times the thickness of traditional melt pressure sensors.


With a choice of six pressure ranges from 0-100 to 0-1000 bar, accuracy to 0.25% FSO and an autozero function, the highly robust IMPACT design offers high stability, high strength and a long working life. The IMPACT series features a separate signal conditioning unit and a 15-5 PH stainless steel isolation diaphragm with a GTP coating for optimum corrosion, abrasion and temperature resistance. A choice of both rigid and flexible stem lengths ensures straightforward installation ...

New Filter Signal Conditioner with Industry’s First Individual Input Ground Isolation


Endevco Corporation, has announced introduction of the Endevco model 4999 low-pass filter signal conditioner, the first in the industry with individual input ground isolation to eliminate ground loops often encountered with multiple channel measurements.  The new model 4999 is particularly well suited for applications such as rotating machinery test cells and the nuclear services industry where a very low noise floor is required, among others.


The 16-channel, 2U rack mounted model 4999 offers an ultra-low-noise design in a 4- or 6-pole low-pass filter conditioner that supplies excitation current to IEPE (ISOTRON®, ICP®) type sensors and remote charge convertors.  Although ultra-low broadband noise is specified at <30µV RMS, the model 4999 actually measures at <15 µV for high accuracy with low-level vibration signals for any data acquisition system.  It is ideal for use with the Endevco model 2771C low-noise remote charge converter and a PE sensor ...
