Description
The Keller 35 X HTC is a high-temperature pressure transmitter for media up to 300 °C. Pressure acts on a flush diaphragm and is carried through an oil-filled capillary, which doubles as a cooling spiral, to the silicon sensor, keeping the electronics below 120 °C. Ranges run from 3 bar up to 1,000 bar with a 0.5% FS error band across the media temperature range.
A microprocessor compensates the sensor mathematically and provides RS485 plus a 4–20 mA or 0–10 V output that can be re-ranged in software. It mounts with a G½ connection and is rated IP65.
Argonmark Ltd supplies Keller instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
