Rosemount 1056 Dual-Input Intelligent Analyzer
Dual input
0/4-20mA current output
Temperature compensated
HART & Profibus DP digital communications available
Description:
The Rosemount Analytical Model 1056 dual input analyzer offers single or dual sensor input with an unrestricted choice of dual measurements. This multi-parameter instrument offers a wide range of measurement choices supporting most industrial, commercial, and municipal applications. The modular design allows signal input boards to be field replaced making configuration changes easy.
The Model 1056 is simple to set up and operate. Menu screens for calibrating and programming are simple and intuitive. The 1056 auto-recognizes each measurement board and a quick start screen prompts users to configure each sensor loop. A high-contrast LCD provides live measurement readouts in large digits and shows up to four additional process variables or diagnostic parameters. The 1056 is available with HART and Profibus DP digital communications. HART models can communicate with the Model 375 HART handheld communicator and HART hosts, such as the AMS Intelligent Device Manager. Profibus units are fully compatible with Profibus DP networks and Class 1 or Class 2 masters.
The Model 1056 accepts single or dual sensor input. Inputs are isolated from other signal sources and earth ground to ensure clean signal inputs for any configuration. Standard 0/4-20mA current outputs can be programmed to correspond to any measurement or temperature. The unit also automatically recognizes Pt100 or Pt1000 RTDs built into sensors for temperature compensation.The Model 1056 is a multi-parameter instrument allowing users to measure pH, ORP, ISE, resistivity, conductivity, percent concentration, chlorine, oxygen, ozone, temperature, turbidity, flow, and 4-20mA current input. Sensors for the Rosemount 1056 are available as accessories. Please contact us if you are unable to find a sensor for your application or require additional information.
