PRECISION DIGITAL INTRODUCES EXPLOSION-PROOF, MULTI-POWERED, PULSE INPUT FLOW RATE METER / TOTALIZER
14/02/2013 Precision Digital Corporation
February 12, 2013 - Holliston, MA - Precision Digital, global leader in digital panel meters and control instrumentation, today announced the PD6830 ProtEx®-RTP Pulse Input Rate / Totalizer. With a rugged, explosion-proof, NEMA 4X enclosure, the PD6830 is designed for quick and easy display of local or remote flow information in hazardous areas or the harshest safe area applications. The unique SafeTouch® through-glass buttons allow operation without removing the cover. Flowmeter k-factor units are automatically converted to the desired display units; this means no conversion factors are needed. The pulse input accepts a wide range of flow transmitter signals, including mV input from a magnetic flowmeter, as well as high frequency signals. The PD6830 includes backlighting and two open collector outputs as standard. The meter has FM, ATEX, CSA, IECEx, and CE approvals and is housed in a rugged, cast aluminum NEMA 4X enclosure."The ProtEX PD6830 is designed for what operators need most...a meter that is easy to read, displays important information about their process, and can be seen from wide angles and a distance," said Jeffrey Peters, President, Precision Digital Corporation. "Other meter manufacturers have lost sight of the fact that users need to be able to see the data, even in hazardous areas. The PD6830 is designed for readability and ease of use, from large character displays to automatic rate conversions."
The PD6830 features an upper display that is 0.7 inches high and shows five digits of flow rate or total. The lower display is 0.4 inches high and shows a combination of flow rate, total, grand total, or a tag with seven alphanumeric characters. The meter is easy to read from a distance, under various lighting conditions, and from wide viewing angles of up to +/- 40 degrees (twice that of competitive models).
Four sensors in the PD6830 operate as through glass buttons for programming and operation without removing the cover in hazardous areas. These SafeTouch® buttons include an energy saving mode to save power, extend battery life, and prevent unintended triggers.
Unit conversions are automatically performed by the PD6830. This means no math or conversion factors are needed. The meter is capable of data logging up to 1024 records in real time. Each record contains date, time, rate, total, grand total, and log number.
The PD6830 is designed to handle a wide variety of high speed inputs and outputs. Inputs include active to 20 mV p-p pulses, open collector, NPN, PNP, TTL, or switch contacts up to 64 kHz. Inputs can be discerned with pulse widths as small as 5 µs. Two open collector outputs are individually programmable for rate, total, or grand total alarms; rate, total, or grand total pulse outputs; retransmission of pulse inputs; quadrature paired output; or constant timed pulse output.
The PD6830 provides flexible power options, including battery, DC with battery backup, DC only, output-loop, or output loop with battery backup. It is housed in a rugged, cast aluminum NEMA 4X (IP68) enclosure that provides three threaded conduit holes and integrated pipe or wall mounting holes. Operating temperatures range from -40 to 75 degrees C.
