Delta Ohm has released a series of analog and digital temperature and humidity transmitters. The HD9817 series feature compact self-contained transmitters with analog (0-1 V) and digital (RS232 and USB) outputs.
The AT9000 advanced transmitter from Yamatake is a microprocessor-based smart transmitter that features high performance and good stability. Capable of measuring gas, liquid, vapour and liquid levels, it transmits 4-20 mA DC analog and digital signals according to the measured differential pressure.
The DMI series flowmeter operates on the magneto-inductive principle. With no protrusions into the pipe, conductive liquids and slurries can be measured with virtually no system pressure loss. The DMI is available with a PEEK or PVDF flow tube and Hastelloy C measuring electrodes are standard.
The Schmidt flow sensor SS 20.260 offers a measuring range of 0-50 m/s and an operating temperature range of up to 120°C. The temperature can be measured with an additional linear output, and a separate temperature sensor is not required. The unit has a robust construction to protect it against impact.
Part of ABB’s FlowMaster family, ProcessMaster incorporates features providing users enhanced performance with reduced complexity. Available in sizes 3 to 2000 mm, the ProcessMaster range offers a wide choice of liner and electrode options, enabling it to meet the needs of demanding applications.
The NWS liquid level switch is designed as a 2- and 3-wire switch and can be universally used in vessels and pipelines. The NWS operates on the tuning fork principle in air at resonance frequency. A piezoelectric crystal is used for excitation of oscillations and for monitoring the actual oscillation frequency.
Interworld Electronics has available the 104-AIO16A multifunction analog I/O board. Its features include 10 analog input ranges, a 1024 sample FIFO buffer, onboard over sampling for additional noise reduction and auto calibration to reduce converter offset and gain errors.
National Instruments has released Single-Board RIO devices that offer engineers and scientists a low-cost, integrated hardware option for deploying embedded control and data acquisition applications for OEMs and machine builders.
Protection tubes and flexible sensors make it possible to replace thermocouples without shutting down the entire process for days or weeks.
The type MIK flowmeters offer four measuring tube widths from G 1/4 AG to G 1 AG and thus four measuring ranges from 0.5-4 to 10-100 L/min. These devices use the magnetic-inductive principle of measurement and are suitable for many applications like the monitoring of additives or cooling agents, consumption measurement or charging.
