Page 7: Introduction
It uses the SDI-12 or RS-232 communications protocols to communicate with an SDI-12 or RS-232 recorder to simplify installation and programming. The CS450/CS455 can be used with an A150 desiccated case allowing the transducer to be connected to a CWS900 wireless sensor or prewired enclosure. -
Page 8: Specifications
The desiccant tube is shipped with a black cap to cover the vent hole. This cap MUST be removed prior to installation. Remember that although the CS450/CS455 is designed to be a rugged and reliable device for field use, it is also a highly precise scientific instrument and should be handled as such. -

CS450/CS455 Pressure Transducer FIGURE 3-3. Connect screen There are three settings that can be changed: SDI-12 address, Pressure/Level Units, and Temperature Units. Double-click on the window of the units to be changed. This will open a Pick Menu box. Select the desired units and Apply the changes (see FIGURE 3-4). -
Page 14: Sdi-12 Transparent Mode
CS450/CS455 Pressure Transducer 3.1.3 SDI-12 Transparent Mode Transparent Mode allows direct communication with the CS450/CS455. This may require waiting for programmed datalogger commands to finish before sending responses. While in the transparent mode, datalogger programs may not execute. Datalogger security may need to be unlocked before transparent mode can be activated. -
Page 15: Rs-232 Connection Via Pc Terminal Software
PC terminal software can be used to communicate with the CS450/CS455 via the RS-232 communication mode. For this example, HyperTerminal will be used (see FIGURE 3-6). The CS450/CS455 is connected to the PC via the A200 (see Section 3.1.1, Using the A200). Upon setup, HyperTerminal will request you enter the Communication connection;... -

Page 17: Sdi-12 Commands
Subsequent communications handle data reporting from the sensor to the datalogger. The SDI-12 protocol has the ability to support various measurement commands. The CS450/CS455 supports the commands that are listed in the following table. TABLE 3-5. SDI-12 Commands SDI-12 Command... -
Page 18: Extended Sdi-12 Commands
CS450/CS455 Pressure Transducer The CS450/CS455 is shipped from the factory with the address set to 0. The address on the CS450/CS455 can be changed by sending an SDI-12 change address command “aAb!”, where a is the original address and b is the new address. -
Page 19: Sample Number
Dislodging Bubbles While submersing the sensor, air bubbles may become trapped between the pressure plate and the water surface, causing small offset errors until the bubbles dissolve. Dislodge these bubbles by gently shaking the CS450/CS455 while it is under water. CAUTION Do not hit the sensor against the well casing or another solid surface while dislodging the bubbles;... -
Page 20: Well Installations
Fasten the cable to the well head using cable ties or a weather proof strain- relief system (CSI #7421). The cable ties should wrap around the cable jacket; never suspend the CS450/CS455 from the connections at the top end of the cable. When securing the cable, care should be taken to avoid cable damage. -
Page 21: Wiring
CS450/CS455 Pressure Transducer For example, if the correct elevation of the water, as measured by a staff gauge or other measurement device, is 2015.50 feet, and the CS450 provides a reading of 5.76 psig, then: 5.76 psig * 2.31 ft/psig = 13.3056 ft. -
Page 22: A150/Cws900
The A150 desiccated case allows the CS450/CS455 to be connected to the CWS900 wireless sensor and then used in a wireless network. FIGURE 5-1 shows the CS450 wired to the A150’s terminal block. The 26972 cable is included with the A150. -
Page 23: Using Crbasic Or Edlog
Dataloggers that use CRBasic include our CR200-series, CR800, CR850, CR1000, CR3000, and CR5000. These dataloggers use the SDI12Recorder() to read the CS450/CS455. A multiplier of 1.0 and an offset of 0.0 yield water level in psig and temperature in degrees C. -
Page 24: Edlog Programming
The CR500, CR510, CR10(X), and CR23X dataloggers are programmed with Edlog. These dataloggers use Instruction 105 to read the CS450/CS455. Your datalogger manual has a detailed explanation of Instruction 105. Please note that Edlog only allocates one input location for Instruction 105. -

3. In the Start Address field, type in the number of the first input location. 4. In the Number of InLocs field, type in 2 and select OK. Below is a portion of a CR10X program that measures the CS450/CS455. The instructions below do not store data in final storage. -

• Check recent data. Every Two to Three Years or on a Rotating Schedule • Send the CS450/CS455 in for inspection and have it serviced and/or replaced as needed. Troubleshooting The most common causes for erroneous pressure-transducer data include: •... - Page 27 CS450/CS455 Pressure Transducer Problem: Transducer appears to be operating properly but data shows a periodic or cyclic fluctuation not attributable to water level changes. Suggestion: A kinked or plugged vent tube will not effectively vent a gauge pressure (Vented) type of device. Normal changes in barometric pressure will appear as water level fluctuations and these types of errors are typically on the order of 1 foot of water level.
