Measure harsh liquids in vented tanks

06_AST4530The AST 4530 liquid level transmitter from American Sensor Technologies Inc. (AST) measures the level of harsh liquids such as slurries, salt water and oil in vented tanks or containers.

It’s made of PVDF material with a PTFE diaphragm, has a submersible PVDF cable, cord grip and housing as well as a conduit connection for turbulent installations in process plants, salt water holding tanks, on-board ships, turbulent tanks and rail cars.

Sensors are certified to Class I Div 1, Groups C and D for use in intrinsically safe areas with an approved barrier.
Compared to ultrasonic and radar sensor technologies, it will not have an offset in output due to foaming, reflectivity and lid angle or proximity to the tank wall.

In plastic tanks, there’s no need to install a metal plate under the transmitter. It’s vented through the cable to the outside of the tank or container so vapour and condensation will not affect the reading or its survivability. And when it’s used for marine and water processing applications, it doesn’t require a sacrificial anode to reduce corrosion over time. It will also survive longer than standard submersible transmitters in applications where bacteria attack metal.

Voltage and 4-20mA output signals allow interfacing for low current consumption or long distance transmission applications.

AST manufactures pressure sensors, transducers, transmitters and switches for pressure and level measurement in Mount Olive, NJ.

New 700G pressure gauges

05_09fluke700GFluke Corp. has broadened its line of precision pressure calibration products with the addition of 14 new 700G Series pressure gauges and two new models of pressure calibrators: the 719Pro and 721 dual range pressure calibrator.

The 700G gauges cover from 10 inH20/20 mbar to 10,000 psi/690 bar and 0.05% accuracy, with new absolute pressure measurement ranges and reference class accuracy gauges and accuracies of 0.04% of reading. Combine 700G gauges with 700PTPK or 700HTPK pump kits for complete pressure testing up to 600 psi (40 bar) with the PTP-1 pneumatic pump, and up to 10,000 psi (690 bar) with the HTP-2 hydraulic pump.

The 719Pro calibrates high accuracy transmitters, pressure switches and pressure gauges. An onboard electric pressure pump generates up to 300 psi (20 bar), eliminating the external hand pump. It also measures, simulates and sources 4-20 mA loop current signals and measures up to 30 VDC. Its internal 24 loop supply powers a transmitter under test.

The 721 with dual isolated pressure sensors takes simultaneous static and differential pressure measurements for gas custody and transfer applications. It’s configured by selecting either a 16 psi (1.1 bar) or 36 psi (2.48 bar) low pressure sensor and adding any of seven high pressure ranges including 100, 300, 500, 1,000, 1500, 3,000 or 5,000 psi (6.9, 20, 24.5, 69, 103.4, 200, 345 bar).

Scanner covers wider area

03_10PFA717R2100The R2100 multi-beam LED scanner from Pepperl+Fuchs handles challenging indoor and outdoor mobile equipment, intralogistics and machine and plant engineering applications where unique surfaces need to be accurately and reliably detected.

Pulse-ranging technology (PRT) combines with Ultra-IR LEDs and multi-beam scan to deliver two-dimensional measurement over an entire area.

The Ultra-IR LEDs deliver an 8 m operating range without a reflector, and they produce a larger light spot than laser emitters – an advantage when detecting objects with irregular surfaces or textures. Sensors with PRT emit a very short, high-intensity light pulse. They calculate object distance based on the speed-of-light constant and time-of-flight of the reflected light pulse. Instead of transmitting a continuous light beam, PRT sensors emit short pulses of high-intensity light up to 250,000 times per second. Compared to a continuous source that uses lasers, the energy density of one PRT LED pulse is up to 1,000 times greater for stable and reliable detection, even at distances of
300 m or more.

Pepperl+Fuchs is a manufacturer of factory and process automation products based in Twinsburg, Ohio.

Streamline surge protection testing

Weidmuller's V-Test
To effectively protect equipment, operators must test surge protection devices regularly. Weidmuller’s V-Test portable unit streamlines testing with the Varitector VSPC pluggable surge protectors.The instrumentation manufacturer says the hand-held, battery-driven unit takes seconds to perform the test, without disconnecting any wiring from the installed surge protection device. Pluggable arrestors feature optional remote status, where the surge protector generates an alarm when the control system has not detected the condition.

This works well with V-Test to confirm the condition of the arrester. Simply plug the arrester module into the the V-Test, enter the 10-digit item number via the keypad, observe the resulting “OK” or “NOT OK” display, and replace a failed arrester with a spare to get the system back in operation.
