Custom Sensors and Technology
Opened in 1980, Custom Sensors & Technology provide robust process monitoring equipment and accessories for a wide range of bioprocessing applications. With experience spanning pharmaceutical and bioprocessing environments, Custom Sensors and Technology have developed monitoring solutions designed to help users achieve greater visibility and control across their processes.
Available with A-I Bioprocessing, the Custom Sensors and
Technology range includes single-use and reusable pressure sensors, pressure transmitters
and process photometers providing
flexible solutions for applications including tangential flow filtration (TFF),
bioreactor pressure monitoring, depth filtration and chromatography.
Whether maintaining sterile workflows with single-use pressure sensors or reducing waste and improving cost-effectiveness with reusable pressure sensors is your priority, there is a solution to suit your bioprocessing requirements.
Why choose single-use pressure sensors?
· Ready for sterile workflows – gamma sterilisation compatible to support use in controlled environments.
· Suitable for demanding bioprocess setups – made of USP Class VI materials
· Cleanroom manufactured – produced in an ISO Class 7 cleanroom, to support clean, controlled deployment
· 100% accuracy tested – ensured confident, reliable pressure sensing for bioprocesses
Why choose reusable pressure sensors?
· Sustainability focused design – durable construction designed for repeated use
· Reduced single-use costs – reusable pressure sensors maintain performance after multiple uses while keeping single-use costs down
· Robust stainless steel or PEEK outer body and replaceable components – made from robust material and M12 cap is replaceable rather than replace complete sensor
Single-Use Process Pressure Sensor
Process Pressure Sensors are intended for measuring the dynamic and static pressures of liquids and gases for both single-use and continuous use bioprocessing applications including tangential flow filtration (TFF), bioreactor pressure monitoring, and depth filtration monitoring. A standard M12 connector integrates directly to our PT1 (single channel) and PT4 (four channel) transmitters that include 4-20 mA, Modbus RTU, TMP outputs, and optional remote display.

Reusable Process Pressure Sensor
Today’s single-use challenge in the pharma and biotech industries is managing large volumes of single-use materials that need to be disposed of or recycled, which has led to escalating costs. Despite this, single-use products remain preferred for their ability to eliminate the high costs associated with cleaning and chemical disposal.

Pressure transmitters (PT1 & PT4)
The PT4 – Pressure Transmitter accepts an input from one to four pressure sensors, load cells, or transducers. The PT4 has a built-in calibration curve that linearizes the connected sensors for better accuracy and outputs the corrected answer though current loops or Modbus (RS-485). The calibration changes per application and is set by Custom Sensors and Technology, however, the calibration curve can be changed by the user through Modbus. For pressure applications, the default ranges are 0-10psi, 0-30psi, 0-60psi, while the full range is -10-100psi. The default values can be changed through Modbus, or defined when ordering the PT4 and will be set by Custom Sensors and Technology. A standard M12 connector integrates directly to the PT4 Pressure Transmitter that includes 4-20 mA, Modbus RTU, TMP outputs, and optional remote display.

Photometers (PX2, PX2-DIN & PX2+)
The PX2+ Photometer is designed for use in continuous process monitoring applications in a variety of industries. The PX2+ is a highly sensitive, easy to use, and compact instrument capable of making absorbance or fluorescence measurements. The PX2+ features 3.2” capacitive touch LCD that allows users to calibrate and view data. Process monitoring equipment is a great investment as economic benefits arise from greater process control and less waste. The PX2+ is designed to alert users when properties of their process stream change and no longer fall within acceptable limits. The ability to monitor process conditions in real-time allows users to observe small changes before they become much bigger problems.
