The TX200™ transmitter utilize a bonded foil strain gage bridge sensor
to detect and continuously monitor pressure in a system. The strain gage
is a resistive element whose resistance changes with the amount of strain
(pressure) placed upon it. Flexing of the diaphragm causes the resistance
change and electronically communicates this via a 4 to 20 mA output signal
or optional 1-5 VDC output signal to a digital meter or gauge, a PLC (pro
-
grammable logic controller) or other device. The TX200B is “fixed range”
while the TX200A is “field adjustable” with a 5:1 turndown ratio (see Part II
– Adjustments).
PROOF PRESSuRE* LIMITS STATED IN THE LITERATuRE AND ON TRANSMITTER
HOuSING MuST NEvER bE EXCEEDED, EvEN bY SuRGES IN THE SYS-
TEM. OCCASIONAL OPERATION OF uNIT uP TO MAXIMuM PRESSuRE IS
ACCEPTAbLE (E.G., START-uP, TESTING). CONTINuOuS OPERATION SHOuLD NOT
EXCEED THE DESIGNATED OvER RANGE PRESSuRE.
*Proof Pressure
The maximum pressure to which a pressure sensor may be occasionally
subjected, which causes no permanent damage (e.g., start-up, testing). The
units may require re-adjustment.
