VELTRON DPT - IO&M Manual
3 – FEATURES
3.1 – ACCURACY
The VELTRON DPT transmitter is designed to maintain an accuracy of ±0.50% of Natural Full Span. For a span of 0 to
0.10 IN w.c., this accuracy is equivalent to an output accuracy of ±0.0005IN w.c. differential pressure or ±6.33 FPM
velocity.
3.2 – PRIMARY SIGNAL NOISE FILTER
To eliminate background noise and pulsations from the flow signal, the VELTRON DPT is equipped with a user selectable
low pass filter.
3.3 – SQUARE ROOT FUNCTION (optional)
When equipped with the square root option, the VELTRON DPT can provide an output signal linear to velocity or volume.
3.4 – CONTINUOUS DISPLAY OF PROCESS (optional)
The VELTRON DPT
transmitter can be optionally equipped with a 3½-digit LCD display to provide a continuous readout
of the measured process in engineering units (Inches w.c., SCFM, lbs/hr, etc.).
3.5 – HIGH TURNDOWN RATIO OPERATION
The VELTRON DPT transmitter, with its high level of accuracy, can maintain linear output signals on applications
requiring velocity turndown of 5 to 1 (equal to a velocity pressure turndown of 25 to 1).
3.6 – HAZARDOUS LOCATIONS
The VELTRON DPT transmitter is Factory Mutual approved for the following:
• Explosion Proof: Class 1, Division 1, Groups B, C, D.
• Dust Ignition Proof: Class II, III, Division 1, Groups E, F, G.
• Suitable for indoor and outdoor NEMA Type 4X hazardous locations.
3.7 – ENCLOSURE
The VELTRON DPT transmitter is packaged in a NEMA Type 4X enclosure with standard industrial process connections.
