TruTorr
Single-use Headspace Pressure Sensor

The TruTorr™ pressure sensing system is a single-use solution for measuring headspace pressure in a single-use container in order to prevent damage from overpressure. The product consists of a disposable pressure sensor, a cable, and a transmitter that is seamlessly integrated into Finesse TruViu™ hardware (RDPD, PLSSmini or PLSS). The single-use sensor not only compensates for temperature, but is self-calibrated for immediate use, based on integrated, gammaradiation- resistant memory chip technology. Simply attach the cable to the sensor, and set your TruBio® DV control system alarm levels or interlocks for bag overpressure, and start your process.

The single-use sensor can be pre-inserted in a disposable bioreactor bag port and irradiated with the bag, in order to both preserve and guarantee the sterile barrier. All wetted materials of the sensor are USP class VI compliant. Each sensor’s certificate of compliance can be downloaded from the Finesse web site.
