The 4-20mA current loop has proven to be a simple, effective, and reliable means of transmitting electronic signals and power on a single pair of wires. Since current is constant for all points in a loop, current loops can transmit lossless signals over kilometers of wiring. Large facilities have widely adopted the 4-20mA signal as a primary means of data transmission to ensure signal integrity.
Digital Panel Meter (DPM) users have always had a difficult choice to make when it comes to their display. While having options available to the industry is necessary, it also creates a complex decision making process.
OTEK Corporation has been pursuing knowledge and implementing practices to go green in the office for many years. A more environmentally friendly and ecologically responsible approach to decision making benefits everyone. In our industry, you are bound to come across some things that are not as gentle to the earth as they could be. Some technologies that were once cutting-edge have been discovered to be quite harmful.
The analog panel meter has been the indicator of choice for many years. The analog meters ground breaking technology, invented by Sir R. Weston in 1843, allowed a meter to be signal powered. Although it was groundbreaking at the time, this same technology presents opportunities for accidents.
Otek Corporation is offering its model HI-QTBS programmable intelligent controller with an explosion proof housing approved for Class I, II, and III, CENELEC, EEx and NEMA 4, 7 and 9 application requirements in the petrochemical, military, mining, pharmaceutical, semiconductor and biomedical industries. The new “EP” case can withstand stea
Otek’s HI-QSLIM series bargraphs feature V/mADC and/or RS232C/485 input. Measuring only 0.95"W x 6”H x 1.8” D, three different models are available with either 51 or 101 segments and a 2-digit display, or a 7-segment, (8) 0.6” digits display with limited alpha characters and 0-9 numerals plus decimal points.
