Robust Industrial Design

Constructed with an aluminum die-cast enclosure and powder-coated finish, the Differential Pressure Transmitter P 34 delivers industrial-grade durability. This ensures longevity even in demanding conditions, paired with high ingress protection (IP65) against dust and water exposure. Its stainless steel machined components further enhance resilience and corrosion resistance.

Accurate and Versatile Measurements

With a scale range of 0-16 Bar and an accuracy of 1.6% F.S., the P 34 transmitter ensures precise monitoring for a variety of applications. Its capacitive sensor is compatible with both liquids and gases, making it adaptable for different pressure measurement tasks in industrial environments. The analog dial allows for intuitive reading at a glance.

User-Friendly Installation and Adjustment

The transmitter is designed for vertical surface mounting and is equipped with 1/4" NPT female pressure ports for secure threaded connections. Adjustable zero and span settings allow users to calibrate the device easily, while the included mounting bracket and connecting pipe facilitate quick setup. Terminal block electrical connections support straightforward wiring.

FAQ's of Differential pressure transmitter P 34:

Q: How should the Differential Pressure Transmitter P 34 be installed?

A: The P 34 is designed for vertical mounting on a surface using the supplied mounting bracket. Ensure the pressure ports are securely threaded with 1/4" NPT female connections, and complete the wiring via the terminal block. Correct orientation and secure fittings are essential for optimal performance.

Q: What types of media can the transmitter accurately measure?

A: This model is built to measure the pressure of both liquids and gases, making it versatile for a wide range of industrial applications. Compatibility with various media ensures reliability across diverse processes.

Q: When is it necessary to use the zero and span adjustment features?

A: Zero and span adjustments should be used during initial setup or routine calibration to ensure the transmitter delivers accurate readings within your specific operating range. These adjustments compensate for installation variances or system drift over time.

Q: Where can the P 34 operate effectively based on ambient conditions?

A: The transmitter operates reliably in ambient temperatures from -20C to +70C. Its IP65-rated enclosure allows use in wet or dusty industrial environments, providing ample protection against harsh conditions commonly found in factories or process plants.

Q: What is the process for electrical connection?

A: Wiring is completed via a terminal block inside the enclosure, with a recommended power supply of 12-36 V DC. Ensure to turn off power during installation and follow standard safety procedures to achieve correct and safe connections.

Q: How does the analog dial display benefit end users?

A: The analog dial display, made of aluminum with clear Pointer and Glass components, enables users to quickly and easily view pressure readings in real-time without additional electronic interfaces, supporting efficient monitoring on the shop floor.
