Sensor đo áp lực CS451

Mã sản phẩm : 1489840752

The CS451 is a pressure transducer for water-level measurements in canals, wells, ponds, harbors, lakes, streams and tanks. It has a stainless-steel case that can be submerged in most canals, wells, ponds, lakes, and streams. The CS451 outputs either a digital SDI-12 or RS-232 signal to indicate observed pressure and temperature. This output can be read by many of our dataloggers. The CS451 replaces the CS450 transducer. The new transducers have a smaller gap between the water ports and the diaphragm so that less air is trapped that the user must remove during deployment. Trapped air causes the transducer's readings to drift as the air slowly dissolves into the water.

Trapped air causes the transducer's readings to drift as the air slowly dissolves into the water. Benefits and Features Quality construction ensures product reliability Rugged stainless-steel case protects piezoresistive sensor Compatible with most Campbell Scientific dataloggers Fully temperature-compensated Low-power sleep state between measurements reduces power consumption Optional weighted nose cone facilitates submersion NPT fitting allows it to be used in closed-pipe applications Quick shipment after receipt of order (ARO Detailed Description The CS451 consists of a piezoresistive sensor and a temperature sensor housed in a 316L stainless-steel case. It has a rugged Hytrel cable that remains flexible, even under harsh environmental conditions. The cable incorporates a vent tube to compensate for atmospheric pressure fluctuations. The vent tube terminates inside a desiccant tube, which prevents water vapor from entering the inner cavity of the transducer. The CS451 has several pressure range options and two accuracy options (see Ordering Info). The standard accuracy option provides ±0.1% FS TEB over the 0° to 60°C temperature range. The high accuracy option provides ±0.05% FS TEB over the 0° to 60°C temperature range and includes a calibration certificate. TEB is the combined errors due to nonlinearity, hysteresis, non-repeatability, and thermal effects over the compensated temperature range, per ISA S51.1. Please note that the high accuracy option is not available for the 0 to 2.9 psig range option. Campbell Scientific offers the A150 Desiccated Case that allows the CS451 to be connected to a  prewired enclosure (see Ordering Information).
