Description
The Keller Preciseline is a high-precision digital pressure transmitter with ±0.1% FS static accuracy and a ±0.25% total error band over −10 to 80 °C (±0.05% / ±0.1% optional). Ranges run from 0…2 psi up to 0…15,000 psi (about 1,000 bar) in gauge, absolute and sealed-gauge versions.
It provides a 4–20 mA or 0–10 V signal together with RS485 (Keller bus or Modbus RTU), includes lightning protection on 4–20 mA models, and has 316L stainless steel wetted parts with NSF/ANSI 61 approval for drinking water. A Preciseline SDI version adds SDI-12 for low-power data loggers.
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.
