Single-Use Pressure Sensors

Pendotech Single-Use Pressure Sensors are designed for teams running small- to mid-scale bioprocessing workflows who need accurate, low-hold-up, single-use pressure monitoring that integrates seamlessly with a PressureMAT™ System (monitor/transmitter),  Pendotech Process Control System (PCS), or third-party pumps and monitors.

When to Choose a Pendotech Pressure Sensor

Best for scenarios like:

• When you need pressure monitoring during depth filtration or TFF/crossflow filtration
• When a single-use, sterilizable sensor is required
• When your tubing runs from 1/8 inch to 1.5 inch ID
• When you need ‐7 to 75 psi measurement accuracy in flexible tubing
• When minimizing hold-up volume is critical to yield
• When you must integrate with existing pumps, controllers, or PAT systems

How the Sensors Integrate into Your Process

Pendotech pressure sensors can connect to:

1. PressureMAT™ System

For teams needing a compact monitor/transmitter with alarms.

2. Pendotech Process Control System (PCS)

For multi-sensor setups or automated control.

3. Third-Party Pumps & Monitors

Pre-qualified for easy drop-in integration.

Outputs:

Data can be sent to a PC or any external monitoring device (PC output comes from PMAT or PCS, not directly from the sensors).

Common use cases

• Multi-stage depth filtration – consistent pressure tracking across filter trains
• TFF / crossflow filtration – maintain TMP without traditional stainless transducers
• Bioreactor pressure monitoring – sterile, single-use compatible
• General upstream & downstream bioprocessing

Compatibility & Operating Ranges

• Pressure range: –7 to 75 psi
• Tubing sizes: 1/8 inch to 1.5 inch ID (luer option available)
• Sterilization: Gamma & x-ray irradiation compatible
• Documentation: Validation guide available

Design & Performance Features

• Unobstructed flow path & no dead legs provides dramatically reduced hold-up volume versus stainless steel transducers or gauges
• Integral 12-inch cable connects to reusable monitor/ transmitter/alarm cable via molded connector
• Suitable for tubing from 1/8 inch to 1.5-inch inner diameter (luer size available separately) or a sanitary flange

Design & Performance Features

Minimal Hold-Up Volume

Unobstructed flow path + no dead legs → reduces product loss during small-scale runs.

Integrated 12-inch Cable

Connect directly to a reusable monitor/transmitter/alarm cable.

Flexible Connection Types

• Direct tubing (1/8–1.5 inch)
• Luer (ordered separately)
• Sanitary flange

Materials, QA, and Compliance

Construction

• Polycarbonate or caustic-resistant polysulfone
• All materials meet USP Class VI

Manufacturing & QA

• Built in an ISO 9001–certified clean room
• Each sensor tested – rejected if out of specification
• No calibration required

Documentation

• Certificate of Conformanceincluded
• Optional NIST calibration certificate

Hose Barb Design: Preventing Leaks

This design reduces the chance of tubing leaks by eliminating a mold parting line.

Why it matters:

• Single barb shaft lets the hose relax behind the barb for a secure drawstring effect
• Anti-rotation device holds tubing in place during twisting or repositioning

For higher-pressure needs:

• BarbLock
• Oetiker clamp
• Both provide 360° radial compression sealing

Sensors for Smaller Scale Processes (Luer Models)

Ideal for applications like:

• Low-flow in-line monitoring (1/8 inch)
• Dead-end measurements using included cap
• Adaptation to 1/4- or 3/8-inch barb fittings with luer ports

Sterility – Polycarbonate version ships sterile for aseptic setups.
