3500 Advanced Temperature Controller and Programmer

Precision control of temperature and process variables

3500 Advanced Temperature Controller & ProgrammerThe latest range of advanced process controllers from Eurotherm provide precision control of temperature and a host of other process variables together with an abundance of advanced options making it the most adaptable product in its class.

The emphasis is on flexibility yet the 3500 controllers still maintain ease of use. A simple ‘Quick Start’ process is used to configure all the basic functions essential to controlling your process. This includes input sensor type, measurement range, control options and alarms making ‘Out the Box’ operation truly achievable. More advanced features are configured using a PC based graphical configuration tool enabling users to pick function blocks from a library then connect them together using soft wiring.

New Dot - Turbine Flow Meter/Monitor

High Accuracy, Long Service Life

Kobold's DOT is a highly accurate turbine flowmeter used to measure the flow of clean, low viscosity liquids. The rugged design with stainless steel construction and tungsten carbide bearings ensures a long service life. The DOT can handle a wide variety of aggressive and non-lubricating liquids. Common application media includes: chemicals, petrochemicals, fuels, and deionized water.

Principle of Operation

The operation principle of the DOT is as follows. A pick-up coil with a permanent magnet core is mounted in the housing adjacent to the rotor blade tips and a magnetic circuit is created by the rotating blades. The rotation varies the pick-up of this magnetic circuit and the flux changes induce a small voltage in the coil. The frequency of this is directly proportional to the rotor speed and the volumetric flow rate.


The DOT is available in NPT threads from ½” to 2”. Standard ANSI flanges are available in ½” to 6” with larger sizes available upon request. Threaded versions are rated for pressures up to 3,600 PSIG and flanged versions are according to the ASME flange rating. The temperature range is from -4 to 176 degrees Fahrenheit, with up to 250 degrees possible with the mV output option. Available outputs include: mV pulse, transistor pulse, analog 4-20 mA, or LCD total, rate/total or batching display with analog and switching outputs.
