Pressure Transducer delivers Water Level Monitoring in Emergency Tank Shower
Applied Measurements were recently contacted by spill control and containment manufacturer Empteezy, to provide a sensor to be used within an emergency tank shower. The emergency tank shower is ideal for use in locations where a constant water supply and adequate water pressure cannot be guaranteed.
To ensure the emergency tank shower is able to provide a flow of 75.7ltrs per minute of water for 15 minutes, fulfilling the ANSI Z358.1 regulations for emergency tank showers.
Once a gravity fed shower is switched on and the water level within the tank drops, both the water pressure and the flow rate at the shower head decreases. In order to achieve the flow rate of 75.7ltrs per minute of water for the full 15 minutes, the emergency tank shower needs to contain a minimum of 2000ltrs of water within the tank.
Applied Measurements provided Empteezy with a Pi600 series pressure transducer. This Pi600 pressure transducer was connected and calibrated to the digital readout scale on the front of the shower, giving an accurate reading of the litres of water remaining in the tank. When the water level falls below the minimum safety level, a signal is sent to the sounder strobe alarm on the front of the shower. This signal has a dual function. Firstly, alerting safety personnel that the water level has dropped below the minimum, notifying them to refill the shower to achieve the required flow rate and water pressure. Secondly, that the shower has been operated and an injured employee may need assistance.
The Pi600 Series of Pressure Transducers
The Pi600 series of pressure sensors are designed for the measurement of gas and liquid pressure across a wide range of general purpose and industrial applications such as hydraulics, medical, research and development, meteorology and food processing. Constructed from stainless steel with a ceramic diaphragm and viton 'O' ring seal as standard, they are designed to be extremely rugged, yet compact in design.
Key Features Include:
* Ranges 0-50mbar up to 0-700bar
* Wide Variety of Outputs: mV/ Volts / mA
* Can be Offered Calibrated in Metres Water Gauge
* Sealed to IP65 (plug & socket) or IP66/68 (Cable)
* Accuracy: <±0.25%/FS (0.1% option)
* Gauge or Absolute Versions
* Various Pressure Port Options (G1/4" male as standard)
* Excellent Chemical and Abrasion Resistance
* Rugged Construction
* Full Customisation Possible
The Pi600 series of pressure transducers come in pressure ranges of 0-50mbar and 0-700bar in absolute or gauge versions, with a wide choice of electrical output signals from its ASIC-based amplifier circuit. These outputs include, 4-20mA, 0-5Vdc & 0-10Vdc, 1-6Vdc and 10mV/V, as well as a ratiometric 0.5-4.5Vdc signal that requires a 5Vdc supply to suit most data loggers. The Pi600 series of pressure transducers can also be supplied with any of our wide range of instrumentation to give you a complete calibrated system.
In addition, the Pi600 series of pressure transducers can be completely customised to suit your application including; custom process connections, alternate case and 'O' ring material for applications where aggressive media is present, and higher IP ratings for more challenging environments.
The Pi600 series of pressure transducers have proved vital in Empteezy's emergency tank shower units, enabling engineers to guarantee the water pressure and flow rate of the units.
