Pressure Sensors

Our offered Product range includes Atmospheric Pressure Sensor and Pressure Measurement Based Tide Sensor.

Atmospheric Pressure Sensor

Range 100 hPa to 1200 hPa
Accuracy +/- 0.2 hPa
Resolution 0.01 hPa
Output Units hPa/mBar, kPa, atm, mm/in(hg)
Calibration Traceability Offered: IMD, NIST

The KDS-021 Sensor measures atmospheric pressure. It employs a ceramic frontend pressure interface with low hysteresis. The digital architecture of the sensor deals with the non-linearity of the frontend very well, ensuring accuracy and long-term stability. Hence, the sensor does not require periodic service or recalibration.

Features:

Compact size
Stable and accurate radiometric acquisition
Averaging of data to improve variance of output
RS485 Digital Output; Analog options available
Suitable for continuous indoor use
Deployed outdoors in weatherproof enclosure
Automatic internal electronics calibration
Individual Sensor multi-point calibration

Pressure Measurement Based Tide Sensor

Range 0 to 20 m
Accuracy +/- 0.05 %FS
Resolution 1 mm of water level
Digital Output: Serial (UART)/ SDI12
Electrical Interface RS485 / RS232 / SDI12

The KDS-121 Sensor measures tides in applications where a stilling well is available in a coastal tidal observatory. The gauge pressure sensor is developed indigenously and is built to exacting specifications. It uses a zero-headloss humidity trap (supplied with the sensor) in the installation to prevent moisture from entering the system. The sensor provides accurate tidal information such as real-time record of wave height and period; the memory capacity and low power requirements permit regular water level recording. It is suitable for use for ocean circulation studies, on structures like jetties, in ports & harbours, for dredging and surveying, and many other marine applications.
