The VT10 controller family is very well suited for any application requiring reliable and accurate temperature control.
The plug in chassis permits rapid replacement without involving any wiring changes.
The controller has two numerical displays for process value (red) and setpoint (green). The green display is also used for comments during programming. Operation is by four membrane keys and is arranged on three different levels.
The VT10 can be programmed as either a single or double setpoint controller. When used as a double setpoint controller it can be used to control two independent heating and cooling loops. Both loops in this case have PID feedback.
The instrument has one or two relay outputs. Options include 4-20mA control output, RS485 and built-in 2-wire transmitter power supply. One output can be configured as an alarm in eight different ways.
Resistance thermometers, thermocouples, mA or voltage inputs can be directly accepted.
Self optimization ensures automatic adjustment of the controller parameters to the process. The ramp function permits a controlled approach to the setpoint.
The standard supply voltage is 85 to 265 VAC.
All connections are made to the instrument through screw terminals.
1/16th DIN (48mm x 48mm), 1/4 DIN (96mm x 96mm) and 1/8th DIN vertical models are available.
Have your recorders ever run out of chart paper or ink? Perhaps, you’ve had paper jams or the mechanical drive mechanism of your recorders acts up from time to time. Maybe you had to actually look for data on some old charts and didn’t have even a little bit of fun doing it.
We have a solution. Our new PR20 is the perfect replacement for your old recorder. It’s DIN cut-out fits in the hole left by most recorders with a European heritage. In minutes it can be programmed for up to six channels of RTD’s, thermocouples, Voltage or mA signals in any mixture and any range.
Because the signals are electrically isolated you will not have problems with the signal from one channel interfering with another channel’s signal.
Isn’t it time to consider an upgrade to those old recorders. Get the benefits of digital technology without the hassle of a PLC or networking approach.
For double security we store data in non-volatile flash memory as well as on the built-in 3-1/2′′ floppy drive. Our included evaluation software runs under Windows to display and graph the data. The data can be exported to spreadsheet programs for further analysis or graphing.
Since the PR20 uses no pens or paper it can save thousands of dollars in operating costs over the life of the installation when compared to conventional recording techniques.
The DIS-3000 digital indicator is a low cost, instrument for displaying one or two temperatures from RTD sensors.
The standard version accepts two RTD temperature sensor inputs. The first value is continually displayed and the second is displayed when a button on the front of the instrument is depressed.
Wet/Dry bulb: The DIS-3000 is a convenient way to monitor temperatures from a wet and dry bulb psychrometer.
Heat pumps: The DIS-3000 is an easily installed and inexpensive way to monitor supply and return temperatures from any cooling or heating equipment. Since it can be powered by a 9 volt battery it can even be used as a portable instrument in a pinch.
The thermostat style surface mount case is quick to install with sheet metal screws and does not require a panel cut-out. You will need a knock out behind the case for the power and temperature sensor connections.
The Ultrasonic Anemometer 2D is designed to detect the horizontal components of wind speed and wind
direction as well as the virtual temperature in two dimensions. Due to its very short measurement intervals,
the instrument is ideal for the inertia-free measurement of gusts and peak values.
In certain weather situations the accuracy of the air temperature measurement (virtual-temperature)
surpasses that one of the classic method where the temperature transmitter is used in a weather and thermal
radiation shield.
The measured data are available as analogue signals and as a data telegram over a serial interface.
The sensors instrument as well as the instrument body are automatically heated so that the measuring
results, in case of critical ambient temperatures, are not affected by ice, snow or rainfall.
The LED option adds a high intensity red LED digital indicator to our pipe sensor for displaying local temperatures. This can be very useful in retrofit work when glass thermometer wells are re-used for HVAC sensors. Previously it was either expensive or impractical to shut down a section of the physical plant while a an extra well was welded in.
Now we have combined two sensors in the same sheath one connected to the indicator and one thermistor or RTD of your choice to connect to the control panel. An RTD can optionally be connected to a 4-20mA transmitter located in the same housing.
Jumpers on the circuit board permit field changes from Fahrenheit to Celsius and permit the 10ths of a degree indication to be converted to full degrees only.
An inexpensive option adds a setpoint alarm which can switch a one amp AC load.
Matched Pairs: On request 1/3 DIN RTD’s provide 1/10th deg C accuracy for energy consumption calculations.
