HYDAC HDA4445-B-040-000 Pressure Transmitter

Product Name: HYDAC HDA 4445-B-040-000 Electronic Pressure Transmitter
Model Number: HDA4445-B-040-000
Brand: HYDAC
Product Category: Hydraulic Pressure Transmitter / Pressure Sensor
Series: HYDAC HDA 4400 Series

Important: The HDA4445-B-040-000 is more accurately described as an electronic pressure transmitter, rather than a conventional pressure switch. HYDAC identifies the HDA 4445-B series as an electronic pressure transmitter. The HDA 4400 series uses a thin-film strain-gauge measuring cell on a stainless-steel membrane and provides an analogue output for pressure monitoring and control. (HYDAC Technology Corporation)

Product Details

The HYDAC HDA4445-B-040-000 is an electronic pressure transmitter from the HYDAC HDA 4400 series, designed for pressure measurement in hydraulic and pneumatic systems.

The HDA 4400 series is intended for mobile and industrial hydraulics and pneumatics. Its pressure measurement cell uses a thin-film strain gauge on a stainless-steel membrane, while the integrated electronics converts the measured pressure into an analogue electrical signal suitable for connection to control and measurement systems such as PLCs. (HYDAC Technology Corporation)

The B version of the HDA 4445 series is associated with a 0–10 V output signal. HYDAC's catalog lists HDA 4445-B variants with 0–10 V output, including the B-600-000 version. (HYDAC Technology Corporation)

For the exact HDA4445-B-040-000 configuration, the model number is also listed in HYDAC-related product/model references. (Wdutech)

For industrial machinery, the transmitter can provide continuous pressure feedback rather than simply acting as an on/off pressure switch.

FAQ

Is HDA4445-B-040-000 a pressure switch?

No. It is more accurately classified as an electronic pressure transmitter. HYDAC lists the HDA 4445 as part of its HDA 4400 electronic pressure transmitter range. (HYDAC Technology Corporation)

What is the output signal of HDA4445-B-040-000?

The B configuration corresponds to a 0–10 V output in the HDA 4445 series. (HYDAC Technology Corporation)

What pressure range is HDA4445-B-040-000?

The 040 designation indicates the 40-bar version in the HDA 4445-B model family. Because complete model-code configurations can vary, confirm the exact nameplate and manufacturer documentation before installation or replacement.

What is the HDA 4445 used for?

It is used to electronically measure hydraulic or pneumatic pressure and provide an analogue signal to monitoring and control equipment. (HYDAC Technology Corporation)

Can it be connected to a PLC?

Yes, the HDA 4400 series is designed to provide analogue output signals suitable for measurement and control systems, including PLC-based applications. (HYDAC Technology Corporation)

Is HDA4445-B-040-000 suitable as a replacement for another HYDAC pressure transmitter?

Potentially, but the complete model code must be compared. Check pressure range, output signal, electrical connection, mechanical connection and other configuration details before replacing a transmitter.
