Pressure transmitters and level probes
The KELLER range covers standard and front-flush pressure transmitters, differential and low-pressure transmitters, submersible level probes, digital pressure gauges and data loggers. Many X-line devices combine RS485 Modbus RTU with an analog output, and intrinsically safe or increased-safety versions are offered for hazardous areas.
Typical industries
KELLER lists oil and gas, water and environment, HVAC, chemistry, food and pharma, and raw material extraction among its industries. Seven Star LLC quotes KELLER transmitters and level probes in Oman and the GCC with the official datasheet for each item.

Which interfaces do KELLER X-line transmitters offer?
The X-line datasheets list an RS485 half-duplex interface with Modbus RTU and the KELLER bus protocol, which can be combined with a 4...20 mA or voltage analog output.
Does KELLER offer hazardous-area versions?
Yes, the 23SY datasheet lists intrinsically safe 23SY-Ei and increased-safety 23SY-En versions, and KELLER also lists Ei series for other transmitters and level probes; check the markings in each datasheet.
How are KELLER level probes used?
The 26Y and 36XW datasheets describe hydrostatic pressure measurement for groundwater, surface water and water or fuel tank level, with IP68 cable glands and water or fuel cable sheaths.
Is Seven Star LLC a distributor of KELLER?
No. Seven Star LLC is an independent supplier in Muscat that sources genuine KELLER products on request and quotes them in Oman and the GCC.
