The STD Universal Pressure Transmitter is an ideal solution to measure the relative or absolute pressure of gases, liquids and vapors because they provide excellent accuracy, linearity and stable performance.
It’s 10:1 turndown technology makes it is possible to re-calibrate the measuring range of the instrument (Example: A 40bar transmitter can be re-calibrated to 4 bar). This greatly reduces the need to keep instruments with various ranges in stock.
The multifunction 5 digit LCD display permits the user to visualize the variation of either the level or the pressure of the process by value, percentage or a real time graph.
The STD provides a 4…20mA analog signal with superimposed communication signal for HART protocol, programable Zero/Span adjustment, decimal point, damping and display mode parameters via three bottons. The sensing element of the unit utilizes a piezoresistive silicone filled 316SS diaphragm. For harsher applications Sitron also offers a thick film capacitive ceramic sensing element in the STD98.
The housings can be rotated to the desired position. The housings also feature an acrylic window so that the display (also rotatable) is always visible.
