The ISC Signal Isolator is a single channel universal isolating transmitter providing true three-way galvanic isolation up to 2000 VRMS. The input signal is isolated from the output by a microprocessor controller optocoupler. The standard instrument accepts a 4-20 mA and 0-10 VDC input signal and produces a scaleable 4-20 mA or 0-10 VDC output signal with an accuracy of 0.1%. Final calibration is achieved using the front of instrument accessible 15 turn zero and span potentiometers.
Lower Murray Water (LMW) in Mildura required a gate to divert sewage flows to catchment ponds. Darren Bennett from LMW was concerned with the traditional square bottom penstocks that had previously been used to control water flows
Cost-effective engineering has enabled the City of Poteau, Oklahoma to achieve major savings while undertaking recent upgrades to municipal wastewater treatment facilities
The latest version of the Strathkelvin Strathtox respirometer can tell users quickly, simply and clearly when the bacteria should be fed less, aerated less and loaded more in an activated sludge or IDEA treatment plant. This is done by measuring their actual respiration rate.
Pulsair is a technology that delivers an efficient, cost-effective, low-shear method of mixing. The system injects a powerful pulse of compressed air (or gas) into the vessel in a way that creates a vertical circular mixing motion and the contents of the tank are quickly blended into a uniform mix. The mixture can be held in suspension with sequentially-timed pulses that require little expense of energy.
Environmental Instruments, LLC has introduced its model FL-3-H handheld dissolved oxygen meter. There are no membranes or electrolyte and the sensor is not damaged by direct or indirect sunlight. It is a fast responding handheld DO sensor and the keypad functions are simple to use, and the ABS instrument enclosure is waterproof, dustproof, chemical resistant and floatable.
The storage and handling of bulk materials such as grain, flour and plastic pellets can be a high-risk activity and demands accurate and reliability level limit detection. A poorly designed high level limit switch may cause an overflow or a spill leading to wastage with an adverse financial and environmental impact. On the other hand, unreliable low-level measurements may cause inventory problems that negative affect a company's bottom line.
The Eutech Alpha 500 series industrial 2 wire transmitter isolates its input source from its 4-20 mA output to prevent electrical noise and leakage from interfering with the output signal and eliminates crosstalk between multiple transmitters in the same loop to ensure a stable and reliable measurement and control system.
The CC640 digital camera is a low powered, digital camera designed to operate either standalone or in conjunction with a data logger and telemetry system. As a standalone camera and image storage device, it can operate automatically via an in-built timer or be triggered by an external 5 V source. Images are stored on a flash card for later retrieval by PC.
With a colourful 5" screen, the 1150 controller provides for up to four and even extendible to eight control channels, has a real-time clock with 50 programs to be created via an onboard or remote program editor, has freely configurable in and outputs, multiple internal and external alarm functions, 2 PID parameter sets per channel and many more features. Another important feature is the recorder capability for easy commissioning and trending of quality.
