Hockey Puck Style:
The TC-003 Digital RTD Temperature Transmitter is a unique device designed to transmit the temperature measured by a PT100 RTD sensor to a PLC digital input. Although it requires only one normal digital 24VDC input on the PLC, it provides an accurate temperature measurement for use in the PLC program.
It is packaged in a standard ANSI 2”, 50mm “hockey-puck” to be installed in the head of normal industrial temperature probe assembly. The TC-003 transmitter is connected to the normal PT100 RTD.
It measures the resistance of the PT100 RTD and then calculates the corresponding temperature. It then outputs the measurement as a low speed serial pulse train to a standard PLC digital input. The PLC receives 16 bits of data in a format ready to load into a 16 bit data register.
The PLC register ends up containing the value of the measured temperature in degrees C x 10. For example if the measured temperature is -5°C the transmitted data will be -50, and if the easured temperature is +10°C the transmitted data will be 100.
Is it compatible?
The PLC digital input does not need to be a high speed or counter type input. Any normal 24VDC digital input is suitable. The rate of data transmission is selected to allow non-time critical operation of the receiving PLC. The shortest pulse time is 100mS, so the PLC needs
to have a maximum scan time of 50mS. This is normally very easy to achieve. A small section of ladder program collects and interprets the pulses in sequence and loads a register with the measured temperature value. There is no particular limit to the number of TC-003 transmitters that can be used with a single PLC. It depends only on the number of inputs and program and data memory available.
Veederline is now re-adopting our QR Code:
A QR Code (it stands for “Quick Response”) is a cell phone readable bar code that can store website URL’s, plain text, phone numbers, email addresses and pretty much any other alphanumeric data.
If you’re not yet familiar with QR codes, they’re similar to the barcodes used by retailers to track inventory and price products at the point of sale. The key difference between the two is the amount of data they can hold or share.
Bar codes are linear one-dimensional codes and can only hold up to 20 numerical digits, whereas QR codes are two-dimensional (2D) matrix bar-codes that can hold thousands of alphanumeric characters of information.
When you scan or read a QR code with your iPhone, Android or other camera-enabled Smartphone, you can link to digital content on the web; activate a number of phone functions including email, IM and SMS; and connect the mobile device to a web browser.
Inductive Linear Transducers for engineering and instrumentation.
The half-bridge technology for 1 to 360 mm stroke. The wide range of inductive linear transducers includes items with 10, 12 and 25 mm outside diameter and for measuring ranges from 1 to 360 mm. The smaller IW 10 and IW 120 series require external electronic modules for excitation and signal conditioning. IW 250 series with 25 mm housings have integral electronics consisting of oscillator, demodulater and amplifier. Analogue output signals are either 0(4) to 20 mA, 0 to 10 VDC or ± 10 VDC for full range or calibrated strokes. The transducers are completely potted to meet protection grades up to IP 68. Electrical connection is made either by leads, plug and socket or through cable glands. Various mechanical configurations are available to suit specific mounting conditions.
The IW 260 displacement transducers operate according to the new principle of fractional inductivity allotment within the hollow coil. Depending on the position of the core the inductivity changes within the corresponding coil section. This kind of layout provides for more position data than the classical half-bridge or LVDT configuration. An integral electronic circuit transforms these data into a signal proportional to the displacement of the plunger core.
The electronic circuit contains an oscillator, a demodulator, an amplifier and in some cases a current output source. Its SMD-design is short-circuit proof and protected against reverse polarity. The sensor system is completely sealed within a non-corrosive steel case to ensure positive protection against vibration, shock, humidity, oil and corrosive matter.
The new principle of fractional inductivity allotment as described above brings about an outstanding increase of the measuring stroke. In comparison to the IW 250 model the useful range of the IW 260 model increases by 70 to 100% based on the same length of the case.
