ABS Tabletop housing for two DPM's
The KOBOLD plastic flowmeters model VKP operate on a special suspended float principle with cylindrical measuring tube and spring-loaded float with orifice. The float in model VKP-3... has slots moulded on the outside, which protect the instrument from soiling by depositing dirt particles. The danger of the float jamming is thus considerably reduced and soiled liquids with a particle size up to 400 μm can be measured without difficulty. In model VKP-2... a sharp-edged orifice in the float renders the instrument less sensitive to changes in viscosity.
The pressure transducers of the 9L series have a compact, robust housing made of stainless steel, giving them outstanding long-term stability for a range of OEM applications. The metal diaphragm is welded on front-flush and gap-free, separating off the piezoresistive pressure sensor, which is made of silicon, from the measuring medium. Every pressure transducer is measured over the entire pressure and temperature profile and is supplied with a detailed calibration sheet
In the 23SX series high-precision pressure transmitters, temperature dependencies and non-linearity are precisely compensated for by means of a mathematical model in the microcontroller.

The fully welded construction without internal seals is suitable for dynamic applications. Only stainless steel is in contact with the media.
Due to their short measuring wavelength and the high temperature range of up to 2,200°C the pyrometers optris CT 1M and 2M are ideally suited for employment in high-temperature measurements of metals, metal oxides, and ceramics. The short measuring wavelength of the infrared pyrometers additionally decreases measuring errors during low or changing emission levels.
The small sensor head allows for easy installation in limited and cramped spaces. Moreover, it reliably measures temperatures even in ambient temperatures of up to 125°C.
The Series 41 X combines the ceramic measurement cell for low pressure ranges with the µP electronics of the digital Series 30 transmitter. The pressure values from the signals of the pressure and temperature sensors are determined by polynomial compensation (see reverse). The values can be displayed and stored on a PC via an RS485 interface and programming can also be carried out.
The transmitters are calibrated to the base range. The PROG30 software permits programming of the analog output signal in each section of the range within the base range (e.g. range 100 mbar. Output 4…20 mA for 20…60 mbar).
With KELLER RS converters K-100 Series, up to 128 transmitters can be hooked together into a bus system and read by means of a PC or laptop. READ30 software allows the current pressure of each transmitter to be read or the pressure activity of several transmitters to be recorded or stored whilst “on line”.

In the high-precision level probe of the 26X series, the temperature dependence and nonlinearity are precisely compensated for in the microcontroller by means of a mathematical model. In addition to the RS485 interface, the measurement results can also be output via the integrated D/A converter as a rangeable analog signal. Extended lightning protection is also available as an option.
The new compact infrared camera optris Xi 410 combines all the benefits of infrared cameras and infrared thermometers.
The Optris Xi 410 has a fast Ethernet interface and can be powered by PoE. This allows for a simple installation, even if the distance from the PC is large. The built-in hot spot finder function can be used to reliably measure moving objects without having to reposition the camera. If the network connection is interrupted or if the connected PC has a problem, the camera immediately switches to the autonomous stand-alone mode which ensures a continuous measurement and alarm. Thus the reliability of problem detection (typically exceeding a threshold in the context of monitoring a fire outbreak) is maintained. Thanks to this unique feature, the Optris Xi 410 is ideal for all safety applications related to fire prevention, detection of critical hot spots, monitoring of industrial equipment and storage of all kinds.
The Optris Xi 410 incorporates a motorized remote focus, controlled by the free PIX Connect software. The resolution of the camera is 384 x 240 pixels with a frame rate of 25 Hz.
