The DCX-CAPA is an autonomous instrument for recording water level in full scale ranges as
low as 20 inches W.C. It features a rugged, gold-plated ceramic diaphragm for outstanding
long-term stability and 316L stainless steel housing with user serviceable battery for long
The internal electronics of the DCX-CAPA employ the latest microprocessor technology, resulting
in high accuracy and resolution for both pressure and temperature measurements.
The use of non-volatile memory for data storage ensures high data security.
The DCX-CAPA is based upon a relative pressure sensor and is designed for submersible
deployment. Through the use of a vented cable, correction for atmospheric pressure variations
is automatic. Therefore, the expense of deploying additional instruments for monitoring
barometric pressure is avoided.
The reference pressure tube, integral to the waterproof cable, is protected from moisture
intrusion through the use of an optional desiccant tube connected to the adapter nozzle, located
in the data port. For remote installations where desiccant maintenance is impractical,
an optional aneroid bellows may be used, with some degradation of accuracy.
