The 25431 Split Mesh Cable Grip is recommended for use in wells to center the cable and to provide a method of suspending the cable, reducing cable stretch.
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.
With the -PT option, the cable terminates in pigtails that connect directly to the datalogger.
-PW
-PW w/Pre-Wire Connector
With the -PW option, the cable terminates in a connector that attaches to a prewired enclosure.
-CWS
-CWS w/CWS900 Connector
With the -CWS option, the cable terminates in a connector that attaches to a CWS900-series interface. Connection to a CWS900-series interface allows the sensor to be used in a wireless sensor network.
The 31648 is a clamp with 1 in. NPT threads that allows the CS451 to be mated with a 1 in. PVC pipe for installations purposes. A 1 in. female adapter socket with FPT threads is needed between the 31648 and 1 in. PVC pipe. This adapter socket is typically available at stores that sell PVC pipe.
The 33815 makes it easier for you to connect wires from multiple SDI-12 sensors into one set of terminals on a data logger. The 33815 uses six DIN-rail mountable (pn 27479) 6-wire terminal blocks. The 33815 jumpers two connectors together at a time (pn 32918). This setup allows up to 11 SDI-12 sensors to be connected to one set of terminals on a data logger.
The 25366 may be purchased to replace a damaged desiccant tube. The CS451 is shipped with this small desiccant tube attached to it. The transducer's cable includes a vent tube that terminates inside of the 25366. The desiccant tube prevents water vapor from entering the inner cavity of the transducer. 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.
The 29137 is replacement desiccant for this transducer's desiccant tube. It provides enough desiccant to fill the tube approximately 2.5 times. The 29137 desiccant has a cobalt-free indicator that is orange and turns green when saturated. Please note: Prior to August 2019, the desiccant used in 29137 had a desiccant indicator that contained cobalt and would change color from blue to pink when saturated.
The 25425 requires an RMA (Returned Material Authorization) from Campbell Scientific. When it is ordered, we will recalibrate the transducer to meet original specifications. Before and after calibration sheets are supplied with the pressure transducer.
The 25479 is the calibration certificate for the pressure transducer. Although every transducer is calibrated, a calibration certificate is not automatically shipped with the sensor. When a customer orders a calibration certificate, the customer will get a calibration certificate that contains calibration information specific to the individual unit.
