610系列 微差壓變送器-德威爾Dwyer
The Series 610 Low Differential Pressure Transmitters are capable of measuring the pressures and flow of air or non-conducting gases at high resolutions. Designed specifically for clean rooms, isolation rooms, and other critical environments, the Series 610 uses an improved all stainless steel micro-tig welded sensor to detect differential pressure and convert this pressure into a linear DC electrical signal by a unique electrical circuit. This unit is ideal for situations when accurate and reliable pressure monitoring is essential. Easy access pressure ports and electrical connections, removable process heads, and detachable terminal blocks make for fast and easy installation. The Series 610 transmitters are available for air pressure ranges as low as 0.1" w.c. full scale. Standard accuracy is ±0.25% full scale (terminal-based) in normal ambient temperature environments. The tensioned sensor allows up to 2 psi overpressure in either direction with absolutely no damage to the unit. The Series 610 transmitters can be ordered as either a base mount or a din rail mount and the option of a digital read out display. In addition, a calibration key can be ordered that allows the user to set zero and span. One key will work on multiple transmitters.
