Several versions of Hamilton’s pH and polarographic dissolved oxygen sensors are offered with Memosens digital sensor technology. This article explores Memosens sensors and their distinctive characteristics.
Inductive Electrical Connector
Memosens sensors possess a proprietary inductive electrical connector and cable. Between the sensor and cable is a corrosion-resistant twist-lock connection. The design is impervious to short circuit complications triggered by moisture, as none of the metal connection points are exposed.
Digital Transmission
The following bi-directional digital information can be conveyed from the sensor to the transmitter: process pH, temperature, and sensor characteristics (such as serial number and part number, calibration data, and operating hours).
The digital nature of the information ensures data stability and eliminates issues related to noise or errors caused by excessive cable flexing and length, commonly associated with traditional analog sensors.
Data Storage
Sensor information (including automatic sensor recognition, calibration history, operating hours, and sensor part/serial number) is saved with the sensor, allowing off-line sensor verification and calibration before use.

Memosens sensors must be connected to a Memosens transmitter, such as the Hamilton H220X MS, which can receive a digital signal and convert it to 4 – 20 mA analog or other outputs appropriate for process control.
Hamilton’s sensors are also compatible with Memosens-enabled transmitters manufactured by other companies.
