This is a high-accuracy temperature & pressure recorder with internal battery and non-volatile memory for deployment at high depths. This is intended for moorings or other long-term, fixed-site applications, as well as shorter-term deployments on nets, towed vehicles, or ROVs. Calibration coefficients are stored in EEPROM, and uploaded data is in ASCII engineering units (°C and decibars). The thermistor has a long history of exceptional accuracy and stability.
The pressure sensor, has a superior new design that is entirely different from conventional 'silicon' types in which the deflection of a metallic diaphragm is detected by epoxy-bonded silicon strain gauges. The sensor employs a micro-machined silicon diaphragm into which the strain elements are implanted using semiconductor fabrication techniques. Unlike metal diaphragms, silicon's crystal structure is perfectly elastic, so the sensor is essentially free of pressure hysteresis. Compensation of the temperature influence on pressure offset and scale is performed by the CPU.
