PRODUCTS MONITORING & METERING
MONITORING PIPELINE PRESSURE
Housed in a compact, environmentally sealed and explosion-proof housing, Rotork’s robust and compact ELB instrument combines pipeline pressure monitoring with intelligent valve control. Designed to collect detailed operational data for optimising performance and enhancing pipeline safety, this continuously monitors upstream and downstream pipeline pressure dynamics to provide early detection of pipeline breaks and initiate automatic valve actuator movement to an emergency position, based on user-defined parameters. Valve actuator control is based on rate-
of-drop (RoD) and rate-of-rise (RoR), plus high and low pressure limits. A remote process shut down (PSD) input with the option to override all functions is available to drive the valve to the fail position.

Ion Science has enhanced its MiniPID 2 sensor with such features as a long-life 10.6 eV lamp that offers 10,000 hours continuous operation. The lamp, which offers a
60% increase in life span and improved stability for more accurate measurement during long-term continuous monitoring applications, will be fitted as standard to all Ion Science 10.6 eV and 10 eV MiniPID instruments. Also new is a self-diagnostic
feature that indicates whether the lamp is failing to
illuminate or the electrode stack is contaminated. MiniPID 2 offers a variety of benefits, including improved temperature stability, greater sensor-to- sensor consistency and repeatable performance. It provides fast, accurate and humidity resistant
detection of VOC (volatile organic compound) gases and is also interchangeable with the original MiniPID.

Technological enhancements such as THD, neutral current and an hour counter to link the energy consumption to the relevant working hours, have been added to Carlo Gavazzi’s EM210 energy meter range. In addition, the new CTV versions are available in two input voltage ranges, MV53 or MV63, and 333mV current signal. Fast and simple to install, these enable current measurements to be carried out by means of the external
split core current sensor which, when fitted, restricts the voltage to the meter to 333mV. By using split core current sensor technology, no primary wiring disturbances are needed in existing installations, therefore it eliminates the need to disconnect or modify the power cables during installation. A selection of variables can be programmed, providing for active and reactive energy measurement or
METERING EXTRUSION FOAMING
For many plastic foaming applications, particularly when low densities and a high level of homogeneity are required, CO2
is an alternative to conventional
blowing agents. Due to its physical properties in liquid form, however, CO2
must be accurately metered and
completely free of gas bubbles. To help, Linde Gases has introduced
the DSD 400 high pressure metering technology for extrusion foaming using CO2
. An extension to the PLASTINUM
Foam E portfolio, this is said to guarantee a constant mass flow and deliver excellent results even during fluctuating extruder pressures or under difficult climatic conditions. This delivers constant, identical foam structures by ensuring a stable mass flow during the continuous extrusion foaming process. It is unaffected by high ambient temperatures and is said to effectively mitigate cavitation damage and scrap end product.

16 JULY/AUGUST 2016 | INSTRUMENTATION
a complete set from six sets of 3-phase variables. Options include: system variables such as W, var, PF, Hz and phase-sequence; single-phase variables including A, PF and THD (A, V, up to 15th Harmonic); relevant phase to phase and phase to neutral voltages and phase currents. The THD can be enabled or disabled by the user. The EM210 can also calculate and display the neutral current instantaneous value. It is available with pulse only or pulse and Modbus output to provide fast and easy data transmission to connect with PC’s, PLC’s BMS or other data acquisition and monitoring systems.

AN AUTOMOTIVE-GRADE BATTERY MONITOR
New from Intersil Corporation is the ISL78610 12-cell lithium-ion (Li-ion) battery pack monitor. This is designed to provide cell balancing and accurate voltage and temperature monitoring to safeguard Li-ion battery packs in hybrid electric vehicles, plug-in hybrid electric vehicles and electric vehicles. This can be used as a
standalone battery-pack monitor or as a redundant back-up device when combined with the high accuracy ISL78600 multi-cell
battery manager, enabling automobile manufacturers to achieve the higher ISO 26262 automotive safety integrity level (ASIL) D rating. According to the company,
this monitors and balances up to 12 cells with accurate voltage readings and diagnostics, enabling designers to make informed decisions based on absolute voltage levels rather than simply receiving a ‘system not OK’ signal indicating an out-of-range condition. Features also include a
voltage reference, 14-bit analogue-to-digital converter and registers for control and data, while connecting directly to a microcontroller through its 2Mbps SPI interface. It also offers four external temperature
inputs, and includes fault detection and diagnostics. The company’s battery
monitoring and management ICs meet the safety, reliability and performance requirements of next generation automotive battery pack systems. Together, the ISL78610 and ISL78600 offer internal and external fault detection such as open wire, over- and under-voltage as well as temperature and cell balancing faults to mitigate battery pack failures. In addition, multiple devices can be daisy-chained together to support systems with up to 168 cells using a proprietary communications system that provides transient and EMC/EMI immunity.
