Level transmitter - Import export

In the high-precision level pressure transmitters of the 36XW-Ei series, the temperature dependence and nonlinearity are precisely compensated for in the microcontroller by means of a mathematical model. In addition to the RS485 interface, the measurement results can also be output via the integrated D/A converter as a rangeable analog signal. Extended lightning protection is also available as an option. Intrinsically safe – suitable for use in explosive atmospheres.

The remote data transmission unit ADT1-Box is encased in a robust, water-tight plastic housing. The LoRa module, which can be configured on a country-specific basis, establishes a connection with the Internet and makes it possible to collect measurement data in a low-cost and energy-saving manner. These autonomous devices can be linked with digital level sensors and pressure transmitters in the KELLER D and X product lines. With three conventional, high-quality AA batteries, the system can operate autonomously for up to 5 years. The LoRaWAN provider can be selected freely or an in-house or open source infrastructure and associated services can be used. The easiest and most convenient way to access the collected data at the end of the transmission chain is via KOLIBRI Cloud from KELLER.

The Gammapilot FMG50 compact transmitter is designed for non-contact point level detection, continuous level, interface and density measurement in liquids, solids, suspensions or sludges. As the first true 2-wire loop powered compact transmitter it minimizes engineering and installation efforts.

The electronic dp Deltabar FMD72 is a differential pressure system, used to measure the pressure, level, volume or mass of liquids in pressurized tanks or distillation columns/evaporators. The high pressure sensor (HP) measures the hydrostatic pressure. The low pressure sensor (LP) measures the head pressure. The level is calculated in the transmitter using these two digital values. The electronic dp system eliminates issues of traditional differential pressure measurements.
