Operation Manual

Thank you for choosing the high temperature melt pressure transducers and transmitters
manufactured by ChengDuSAND Electronic Co.Ltd. We constantly striveto offer youthe most
satisfied products andservices.
Through 20 yearsof constant developmentand improvement, the measurement accuracy
and service lifeof melt pressuretransducers and transmittersare significantly improved.We used
self-developed new corrosion resistant diaphragm organization of production to reduce
temperature drift andto make theservice span increasedby 5 to10 times andto be usedboth in
strong acid and strong alkali environments since 2000. At present, we continue to maintain the
domestic industry-leading R&D and manufacturing technology level, and in some areas to
achieve and exceed the level of international counterparts. The products have been exported
large quantities tothe European Unionand the NorthAmerican market.
PT Series Meltpressure transducers and transmitters are used in chemical fiber, plastic,
rubber and other high-temperature resistant fluid pressure measurement and control field. This
series products absorb the advanced technology of foreign counterparts products , using
imported raw materialsand key componentsfor production, withstable production organization,
reliable performance, highaccuracy, strongoutput signal ,excellent dynamic performance,high
temperature resistant andzero drift small,etc. PT Seriestransducers and transmitters used with
our company's PSSeries intelligent pressuregauge can meet variety of differentusers ' pressure
measurement and controlrequirements .It canalso be usedwith import pressuregauges (such as,
Dynisco) without any adjustments or modification. PT Series Melt pressure transducers and
transmitters can also be replaced withsimilar import products(such as, Dynisco,GeFran, etc.)
Directly.

Right Wrong WrongWrong
1) Holes must be punched strictly in accordance with dimensions of installing holes for virgin
installation. Installing holesmust be thoroughlycleared in after-installations;
2) Our companyprovides special toolsfor drilling andclean holes;
3) Test system should be inspected beforeinstalled to confirmthat the measurementaccuracy of
transducer/transmitter, themethod described inthe second tableinstructions;
4) Disassembly and installation should be conducted in hot state (material melting state).the
probe should be cleaned immediately when dismounting. Keep the probe clean. Be careful
with probe;
5) Conduct hot-line calibration with pressure gauge. When transducer/transmitter reaches full
thermal equilibrium after1.5 hours installed, the details pleasesee the calibration method of
second instrument. The PS series intelligent pressure gauge our company produced has the
automatic hot statecalibration procedures, pressSET button andCAL button and then loosen
CAL button until the pressure display zero pressure in thermal equilibrium to automatically
calibrate the testsystem;
6) Transducerand transmitter shouldbe kept indry environment whennot used.
