Single Use Pressure Sensors

PendoTECH’s Single Use Pressure Sensors measure static and dynamic pressure of gases and liquids in your biopharmaceutical processes – accurately and cost effectively. Robust enough to be repeatedly cleaned and inexpensive enough to be utilized in disposable applications, our Single Use Pressure Sensors deliver a dependable alternative to stainless steel pressure transducers. The sensors feature PendoTECH High Accuracy Pressure (MEMS-HAP™) chips and are perfect for filtration and chromatography processes, monitoring of glass and disposable bioreactors, filling operations and more. They are available in caustic-resistant polysulphone to withstand sanitization processes. PendoTECH’s pressure sensors, which are qualified for use up to 75 psi, are compatible with PendoTECH’s PressureMAT™ monitor/transmitter, PendoTECH’s Process Control Systems or other pre-qualified third-party monitors.

Single Use Pressure Sensor Data Sheet

The pressure sensors can be integrated for pressure measurement and control with either a PressureMAT™ System (monitor/transmitter) or a PendoTECH Process Control System, depending on the number of sensors and process requirements. The data collected by these systems can be output to a PC or another data monitoring device. They also can be integrated into other pre-qualified 3rd party pumps & monitors. The pressure sensors are very accurate in the pressure ranges typically used with flexible tubing and are qualified for use to 75 psi.

Process Scale Pressure Sensors

  • Applications include multi-stage depth filtration, TFF/crossflow filtration, and bioreactor pressure monitoring and many more
  • Available for use with tubing from 1/4 inch to 1 inch inner diameter (for luer size see below) or a sanitary flange
  • Unobstructed flow path & no dead legs provides dramatically reduced hold-up volume versus stainless steel transducers or gauges
  • Qualified for use in the range from -7 to 75 psi
  • Compatible with gamma irradiation
  • All materials meet USP Class VI
  • Integral 12 inch cable connects to reusable monitor/ transmitter/alarm cable via molded connector
  • Each sensor is tested for quality and accuracy during manufacturing and rejected if out of specification (no calibration required)
  • Manufactured in a clean room in an FDA registered, ISO 13485 facility
  • May be repeatedly cleaned and reused
  • Low cost
  • Sensors may be autoclaved one time Polycarbonate material or caustic resistant polysulfone (please review Application Note- Autoclave of Single Use Pressure Sensors)
  • Certificate of quality included with lot certification; individual NIST Calibration Certificates are optional
  • Maybe non-invasively tested in-place with the PressureCHECKER™ device

Hose Barb Design Features

The design features no mold parting-line where the tubing is secured, which can be a source of leaks. The single barb shaft provides space for the hose to relax behind the barb, causing the tie-wrap to work like a drawstring. A tie-wrap placed over the antirotation device (designed by Eldon James Corp.) will lock the tubing, preventing it from becoming loose by a twisting motion. If a more secure fitting than a tie-wrap is required for higher pressure, either a BarbLock or Oetiker Clamp can be used, and they both give an very secure 360° radial compression seal.

PendoTECH Pressure Sensors – for Smaller Scale Processes

The luer sensors are offered in polycarbonate and polysulphone and have a male/female luer lock inlet/outlet ports and come with a cap on the female luer port for dead-end applications. With the universal luer fitting, they can be adapted to processes in different manners. A couple of examples are they can be used in-line at low flow rates (1/16 or 1/8 inch tubing) or on a 1/4 or 3/8 inch barb fitting with luer port.

The polycarbonate version is available sterile for aseptic connection to a setup where this would be useful.
