Keller RFID Pressure / Transponder Data Logger Series 21 D(C) RFID

Keller RFID Pressure / Transponder Data Logger Series 21 D(C) RFID

4+ Weeks Del.

Quick Overview

The Keller Series 21 D RFID  pressure transponder / data logger combines a piezo resistive pressure sensor with RFID technology to allow wireless reading and collection of pressure measurements, and in the DC version, downloading of logged data. The standard RFID unit is self powered. The DC, data logging version has a small internal battery which can power the device for up to 5 years assuming a measurement rate of 1 reading per minute. A range of RFID reader units and software is available for these devices. Measurement ranges available are from 0-3 to 0-1000 Bar, with a total error band of 0.5% between 0-50°C.

Details

The series 21 D RFID combines Keller's tried and tested series 21 pressure sensor with an RFID transmitter (radio frequency identification) wireless technology.

The D line piezoresistive transmitters used to measure pressure are based on Keller’s own chip-in-oil technology. The laser-welded, hermetically sealed stainless steel housing, which is filled with oil for pressure transmission, contains the pressure transducer and the ultra energy efficient compensation electronics with I2C interface.

Series 21 D RFID: Passive RFID pressure transponders Series 21 D(C) RFID Pressure Sensors
The plastic cap houses the interface to the pressure transmitter and all RFID components including the antenna. The scanner provides the power required to log instantaneous values.

Series 21 DC RFID: RFID data loggers

These pressure transponders come with extra data recording functionality. The integrated battery allows data to be measured and stored. Stored measurements are transmitted wirelessly and exclusively via the RFID interface.

Features

  • Extremely resistant to environmental impact
  • Ultra-compact stainless steel housing, also available in Hastelloy C-276
  • High accuracy, outstanding long-term stability, hysteresis-free
  • Temperature displayed alongside accurate pressure reading
  • Pressure ranges from 3 to 1,000 bar
  • Freely programmable measuring point numbers (8 alphanumeric characters)
