Overview
The CS450 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 CS450 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 data loggers.
Key Advantages
Ideal for long-term deployment in harsh conditions
Technical Description
The CS450 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 CS450 has several pressure range options and two accuracy options . 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 CS450 to be connected to a CWS900 Wireless Sensor Interface (for use in a wireless sensor network) or to be connected to a prewired enclosure (see Ordering Information).

Replacement Desiccant Tube for Pressure Transducers
The transducer's cable incorporates a vent tube that terminates inside of the 25366 desiccant tube. The 25366 is offered as a common accessory for customers who want a spare desiccant tube. The 25366 desiccant has a cobalt-free indicator that is orange and turns green when saturated. Please note: Prior to August 2019, the desiccant used in 25366 had a desiccant indicator that contained cobalt and would change color from blue to pink when saturated.

Calibration with Data for the CS450, CS451, CS455, or CS456
The 25425 requires an RMA (Return Material Authorization) from Campbell Scientific. When it is ordered, we will calibrate the CS450 to meet original specifications. Before and after calibration sheets are supplied with the pressure transducer.
Orderable27442
CS45X Recabling Service
Customers can get their transducer recabled but they must get an RMA (Return Material Authorization) and return the transducer to Campbell Scientific. The 27442 is a kit used by Campbell Scientific's Repair Department to recable the transducer. Please note that, the total cost for recabling the transducer is the price of the 27442 kit, plus labor charges, plus the per foot price of the cable.

Compatibility
Desiccated Case
The CS450 can be used with the A150. The A150 is a small, self-contained junction box that allows the CS450 to be connected to a continuation cable, a prewired-enclosure connector, or a CWS900-series wireless-sensor connector. Connection to a CWS900-series interface allows the CS450 to be part of a wireless sensor network.
