Description
The Rosemount 1056 is a line-powered, dual-channel transmitter for liquid analysis. Each of its two isolated channels takes a plug-in measurement board for pH/ORP/ISE, contacting or toroidal conductivity, chlorine, dissolved oxygen, ozone, turbidity or a flow/current input, so one ½ DIN unit can handle two different measurements.
It provides 0/4–20 mA outputs with optional HART or Profibus DP, and with the 24 V DC or universal AC power options it adds four 5 A alarm relays. The polycarbonate Type 4X/IP65 housing mounts on a panel, wall or 2 in pipe, and Quick Start programming with automatic board recognition keeps commissioning short.
Argonmark Ltd supplies Rosemount instruments across Bangladesh — to pulp and paper mills, water and effluent treatment plants, chemical, textile, food and power plants in Dhaka, Chattogram, Gazipur, Narayanganj and beyond. Send us the model, measuring range, process connection, wetted materials and output you need, and we will confirm the right configuration, lead time and price.
