DP & Flow Transmitter
MICRO-BAR DIFFERENTIAL PRESSURE/FLOW TRANSMITTER
Micro-Bar electronic transmitter incorporates a capacitance based differential pressure cell for sensitive measurement on Air or other dry gases. Designed for gas flow measurement applications on extraction or ventilation systems, the micro based electronics uses calibration formulae required for Flo- Bar Averaging Pitot tubes, Orifice Plates or other standard DP based sensors. Simply installed adjacent to the flow line, standard pressure impulse tubing links the sensor directly to the Micro-Bar unit. Flow rate, flow units and alarm status are displayed on the two line LCD: external signal transmission is via the 4-20mA loop power,with separate alarm relay and totaliser pulse.
With simple adjustment over a 5:1 full scale pressure range available to the operator on site, the Micro-Bar suits varying process conditions or output scaling requirements. The micro based electronics simplifies site setup procedures, allowing adjustment of alarm output set points, totalisation pulse rate, averaging time and zero checking.
Micro-Bar is applicable to measuring pressure differentials on operating theatres, clean rooms or glove boxes, to monitor system performance and provide alarms. On process monitoring, Micro-Bar is used for air filter blockage monitoring and burner control on furnaces. For these duties, the display shows the pressure drop directly.
FEATURES
Platon Averaging Pitot Tube: Flo-Bar
The Flo-Bar is an Averaging Pitot Tube flow sensor for use on pipes/ducts or chimneys. Differential pressure created across the Flo-Bar has the standard square root relationship to flow rate, making a simple, removable sensor for installation or retrofit on flowlines of any size.
The unique design of the Flo-Bar profile provides a high accuracy, wide rangeability sensor: the standard integral manifold allows simple process isolation and easy installation of a DP measurement cell.
Platon In-Line Pitot
The In-Line Pitot "Flo-bar" are Stainless Steel pipe sections with welded-in pitot probes, available for ½" to 2" pipes. They are supplied fitted with ¼" ball valves to provide process isolation.
UKAS and Traceable Calibration
Roxspur Measurement & Control Ltd is an ISO 9001:2008 company, we offer UKAS and traceable calibration under BS/EN ISO17025 accredited procedures. Our certificate generation systems are purposely geared to meet the strict and specific requirement of the Aerospace industry.
Calibration
Based at our factory in Sheffield our accredited laboratories are available to provide either on-site or in-house calibration to either UKAS or national standards. We cover Temperature (up to 2,200ºC), Pressure (up to 1,200 bar), Flow (up to 2,500 L/min) and Electrical parameters and provide certification using the latest technology.
Our team of experienced on-site engineers hold accreditation for the on-site calibration of equipment including autoclaves, furnaces, thermocouples and probes, scales and balances, ovens and chambers, indicators and controllers, pressure and electrical. We cover the full spectrum of industry sectors. All calibration standards used meet the requirements of Table 3 of AMS 2750D, whether in the laboratory or on site, ensuring full compliance with the specification.
