Instructions for use, multi-configuration differential pressure sensor

Multi-Sense Model 260 multi-configuration differential pressure sensor ▲ Single vector range: 0.1-10 in. WC to 0.25-2.5 kPa FS ▲ Bidirectional range: 0.1-10 in. WC to 0.25-2.5 kPa FS ▲ Suitable for air or The 260 series micro-differential pressure sensor of non-conductive gas, measures the differential pressure or gauge pressure (static) pressure, and converts this pressure change into the HH series micro-differential pressure sensor to measure the differential pressure or the gauge pressure (static) pressure, and To convert this pressure change into a proportional electrical output, either one-way pressure range or two-way pressure range can be selected. The 260 series provides high-level analog outputs of 1 ～ 5VDC, 0 ～ 5VDC, 0 ～ 10VDC and 4 ～ 20mA that can be selected on site. Used in building energy management systems, these sensors can provide parameters for controlling building pressurization and air flow by measuring pressure and flow. The 260 series pressure sensor can be set as low as 0.1in.W.C. of full scale (about 25Pa). The static accuracy at room temperature is ±1.0% FS. The temperature compensation of zero point and full range is ±0.02% FS/ 0F (0.036% FS/℃). Model260 uses all stainless steel argon arc welding sensitive components. The tensioned stainless steel film and the fixed insulated stainless steel electrode form a variable capacitor. The positive pressure causes the diaphragm to move toward the electrode, and the capacitance value increases. As the pressure decreases, the diaphragm moves away from the electrode and the capacitance decreases. The change in capacitance is detected by Setra's unique electronic circuit and converted into a linear DC signal. Optional pipe static probe range with sealing gasket.
