PTX 1290 Series Wastewater Submersible Pressure Transmitter

PTX 1290 Series Wastewater Submersible Pressure Transmitter

The 1290 Series submersible/depth pressure transmitters are specifically designed for the wastewater, pump/lift station application. The all-titanium construction assures excellent life in the most hostile environments, including corrosive and hazardous chemical applications. Druck backs its titanium construction with a 5 year corrosion warranty. Standard vented cable is polyurethane.

The 1290 Series pressure transmitter is similar to Druck’s field proven submersible sensors with the exception of the pressure port. It is equipped with a flush teflon-coated elastomeric diaphragm that reduces the likelihood of grease or biosolids buildup. The pressure transfer medium is a silicone grease that maintains its elasticity between -40 and +250°F.


NOTE: This product is only available in the United States, Canada, and Latin America. - US IS approvals only

Pressure Measurment

Operating Ranges Any range from 1.75 mH2O to 15 mH2O
Overpressure The operating pressure range may be exceeded withnegligible effect on calibration by4x FS for ranges = 7 mH2O2x FS for ranges > 7 mH2O (28 mH2O Maximum)
Pressure Media Fluids compatible with Titanium, PTFE-coated nitrilerubber and Polyurethane
Excitation Voltage 9 to 28 Vd.c.
The minimum supply voltage (VMIN) which must appear across the pressure transmitter is 9V and is given by the following equation:- VMIN = VSUP - (0.02 x RLOOP)
Output Signal 4 to 20 mA



Accuracy Combined effects of non-linearity, hysteresis and repeatability ±0.25% FS BSL
PTX 1290 Series Dimension Diagram
Zero offset and Span Setting Maximum ±0.1 mA
Long Term Stability Maximum 0.2% FS per annum
Operating Temperature Range -20 to 60 ºC
Compensated Temperature Range -2 to 30 ºC
Temperature Effects ±1.5% FS for ranges above 7 mH2O increasing prorata for ranges below 7 mH2O
Insulation 500 Va.c. = 5 mA tested for 1 minute
Intrinsically Safe Certified (BAS 01ATEX1018X) for use with IS barrier systems to EEx ia IIC T4 (-40 = Tamb = 80ºC) for cable lengths to 300m maximum
CE Marking CE marked for electromagnetic compatibility, pressure equipment directive and potentially explosive atmospheres



Electrical Connection Vented Polyurethane cable with integral Kevlar strain relief cord rated to 54 kg load. Water Ingress protection IP68 to 700 mH2O
Cable Lengths To be specified as required in 1 m increments
Weight 140 g nominal (excluding cable)
Caution Do not remove the retaining ring that holds the elastometric diaphragm in place. This will void the calibration and could result in loss of the silicone pressure transfer compound.
