Description
The APT100 is housed in an IP65 die cast enclosure in
order to provide the ruggedness demanded of plant transmitters. The sensor
is available with a choice of connection flanges to ensure easy compatibility
with plant such as freeze driers, vacuum coolers, distillation and de-odouriser
towers, etc. The sensors are capable of overpressure to 2 bar, even those
with a full scale of 0.050mb.
The temperature controlled sensor has remarkable linearity and repeatability,
providing the best available accuracy for sub-atmospheric process monitoring
and control. The transducers are mains powered and have optional signal
outputs of 10Vdc, 4-20mA for mains powered APT's and additionally, RS232
or RS422/485 for dc powered instruments.

The APT is ideally
suited to monitoring vacuum processes where the media temperature varies
during the process being enclosed in its own hermetically sealed temperature
controlled environment, the Barocel continues to measure accurately when
most other gauges are grossly at error. The APT101 with its IP55 enclosure
is a fully compatible retrofit package for earlier rectangular capacitance
manometers, whereas the IP65 enclosure of the APT102 brings capacitance
manometer performance to such an environment for the first time.
