Digital Sensors - Absolute Pressure

Absolute reference digital pressure sensors with RS485, RS232 and USB interfaces for connecting to desktop and laptop PC computers.

High precision pressure transducer with an accuracy of 0.05% full scale including temperature errors over +10 to +40 deg C. Available in pressure ranges from 1 to 1000 bar gauge or absolute with a RS485 digital interface plus an optional USB or RS232 converter cable for connecting to a desktop or laptop PC.

High precision RS232 or RS485 interface pressure sensor for use as a reference standard for calibration or research purposes. An accuracy of ±0.02% FS is achieved over single or dual scaled pressure ranges from 350mb up to 400 bar gauge or absolute.

Very highly accurate RS232 or RS485 serial interface pressure transducer with an accuracy of ±0.01% full scale achieved over pressure ranges from 25 mb up to 400 bar gauge or 350 mbar up to 400 bar absolute, including barometric & vacuum ranges.

Highly accurate digitally compensated pressure transducer with G1/2 male flush pressure port. Designed for use on viscous media or where a flush face is required for easier cleaning when used with food, drink or hazardous substances such as Oxygen. Select pressure ranges as low as 1 bar or as high as 1000 bar. Standard digital output is RS485 which can be converted to RS232 or USB via optional converter cables.

Digital pressure sensor with 3 separate channels for measuring P1, P2 and DP readings plus 2 temperature channels measured on the sensing diaphragm which is in close contact with the media. Base pressure ranges from 3 bar up to 300 bar with high accuracy.

SDI-12 protocol transducer for sensing water depth level and temperature in seawater, brackish water, tidal water, saline water or leachate. The digital interface conforms to the requirements of the SDI12 support group and can be used with environment monitoring equipment which supports the SDI12 digital communications interface. A high corrosion resistant ceramic diaphragm is fitted a standard and stainless steel 316L, Duplex or Marine Bronze housing materials can be chosen to suit the application requirements. Measure salt water depth in the ranges starting from 0-10 metres up to 0-100 metres, including absolute non-vented ranges from 1.5 bar up to 10 bar absolute.

Combined pressure and temperature sensor with a 1200 baud rate serial data interface as defined by the SDI-12 support group. The S12S is a submersible probe used for monitoring water level and temperature. The SDI-12 digital interface is specially designed for low power, battery operated instrumentation such as on-site environmental dataloggers. Measure the rise and fall of water levels in ranges from 0 to 2 feet up to 0 to 300 feet of water column.
