关于该商品的更多信息
These low-cost mass flowmeter controllers use a thermal gas flow sensing technique that results in highly accurate readings and repeatability. The controllers accept a 0 to 5 VDC input signal for remote valve control. Controllers with LCD display feature a potentiometer for manual valve control. The 3 1/2"-digit display tilts up to 90° for easy viewing. Front panel dip switch lets you select one of the factory programmed gases: air or nitrogen.
All controllers require a combined power supply/input/output cable. This cable combines three functions into one unit: power source, plus input or output of 0 to 5 VDC signals. Use the input signal for remote valve control; use the output signal for datalogging or controlling other instruments. Order the power supply/input/output cable separately.
Wetted materials are anodized aluminum, 316 stainless steel, brass, Viton®, and acetal. Maximum pressure drop across the unit is 15 psi at maximum flow. Differential pressure should not exceed 45 psi.
These precalibrated flowmeters operate at inlet pressures between 5 and 40 psi and at gas temperatures between 64 and 77°F (18 to 25°C) while maintaining the stated ±1.5% full scale accuracy and linearity. When operating beyond 5 to 40 psi, add ±0.02%/psi full scale; if operating beyond 64 to 77°F (18 to 25°C), add ±0.15%/°C full scale.
