Differential Pressure Transmitter (PEL)

Application: The PEL pressure transmitter is designed for detecting pressures and pressure differences in air handling systems. It provides accurate pressure measurements crucial for monitoring and controlling airflow in HVAC systems.

Features:

  • Temperature compensation ensures precise pressure measurement across varying ambient temperatures, enhancing reliability in different environmental conditions.
  • The transmitter zero point is maintained accurately through regular automatic zeroing, eliminating potential zero-point drifting. This feature reduces the need for recalibration, minimizing maintenance requirements.
  • Process disturbances, such as turbulence, can be mitigated by selecting a suitable time constant (2 s or 8 s), optimizing system stability and performance.
  • The M models feature RS-485 connection for Modbus RTU communication, allowing for seamless integration into control systems. ML-SER tool facilitates Modbus settings during commissioning.
  • N models come with a backlit display, offering clear visibility of measured values. The display resolution is 0.1 Pa for values below 200 Pa and 1 Pa for values over 200 Pa, providing accurate readings.
