Hach Orbisphere 510 Multichannel Gas and Dissolved Gas Analyzer

Overview

The Hach Orbisphere 510 is a multichannel gas and dissolved gas analyzer that runs up to three Orbisphere sensors from one instrument. It accepts Orbisphere luminescent dissolved oxygen (LDO) sensors for O₂, electrochemical sensors for O₂, O₃ and low levels of H₂, and thermal conductivity sensors for selective measurement of CO₂, N₂ or H₂. Hach positions it for accurate, repeatable trace-level gas analysis with a high level of data management, which is why it is found on boiler feedwater, pure water and beverage lines.

Seven Star LLC supplies the Hach Orbisphere 510 to power producers, desalination and water treatment plants, industrial steam users and beverage plants in the Sultanate of Oman and the GCC. Our Muscat engineers help you match the controller to the right sensors, mounting version, power supply and communication options for each measuring point.

Operating Principle of the Hach Orbisphere 510

The Hach Orbisphere 510 is the electronics and user interface; the measurement itself is made by the sensor fitted to each channel, and resolution, accuracy and response time are therefore set by the sensor chosen. An LDO sensor measures oxygen by luminescence quenching, an electrochemical sensor measures the gas through a membrane-covered cell, and a thermal conductivity sensor separates a target gas such as CO₂ or N₂ by its effect on heat transfer. The controller can combine an LDO sensor with a thermal conductivity sensor when CO₂ must be measured alongside oxygen.

During configuration the operator can remove common interference effects from CO₂, H₂S, H₂, N₂, humidity, salinity and chlorinity. For electrochemical oxygen sensors Hach lists chlorinity and salinity correction, CO₂ and H₂S insensitivity and H₂ correction, plus O₂/N₂ compensation for electronics applications. A configurable thermal cut-off protects the sensor when sample temperature exceeds the configured limit.

Engineering Design of the Hach Orbisphere 510

Three mounting versions of the Hach Orbisphere 510 are offered. The panel version has an aluminium enclosure rated IP65, measuring 156 x 220 x 253.5 mm and weighing 2.9 kg. The wall and pipe version uses a stainless steel enclosure rated IP65 / NEMA 4X, measuring 230.5 x 250 x 160 mm and weighing 3.8 kg. A portable aluminium version, also 3.8 kg, runs from 5 V supplied through an external 85-264 VAC adapter and can take an optional four-hour battery pack. Fixed versions accept universal 100/240 VAC at 50/60 Hz (25 VA) or 10-36 VDC (25 W).

The operator works on a colour TFT touchscreen that shows concentration, a trend graph, diagnostics, alarm status and historical data. Gas concentration can be shown for the gas or liquid phase in several units, together with external and barometric pressure and sample temperature in K, °C or °F. Product lists and global settings can be moved between instruments through USB-client or USB-host ports, which simplifies commissioning when several analyzers are installed on one site.

Key Features of the Hach Orbisphere 510

Hach lists the following functions for the Hach Orbisphere 510.

• Up to three Orbisphere sensors on one controller, with a maximum of two thermal conductivity sensors.
• Full compatibility with Orbisphere electrochemical sensors, including Smart sensors that store their own calibration and can be calibrated in the laboratory before installation.
• Three smart 0/4-20 mA outputs (500 ohm), programmable as linear or tri-linear and able to carry diagnostic information.
• Three measurement alarm relays and one system alarm relay, each rated 2 A at 30 VAC or 0.5 A at 50 VDC.
• RS485 and Ethernet communication as standard, with Profibus DP as an option.
• Data storage of up to 10,000 measurements, the last 1,000 operator actions and the last 50 calibrations, in rolling-buffer or store-once mode.
• Five levels of password protection to limit configuration and data access.
• Internal diagnostics with maintenance and calibration reminders and adjustable alarms for out-of-specification events.

Industrial Applications

Hach lists food and beverage, industrial water, pure water applications and non-nuclear power for this analyzer. In Oman the Hach Orbisphere 510 is well suited to trace dissolved oxygen on condensate and boiler feedwater at combined-cycle power stations, at independent water and power projects in Barka, Sohar, Sur and Salalah, and on the steam systems of refineries and petrochemical plants. Because one controller handles up to three channels, a single Hach Orbisphere 510 can cover several points of a water-steam cycle.

Beverage producers use the same platform to control oxygen pick-up and CO₂ content in product and process water. Seven Star LLC supplies the Hach Orbisphere 510 with engineering support in Muscat and can quote compatible Orbisphere sensors, flow chambers and spare parts so a three-channel point can be ordered as a single package.
