Water pressure transmitter with an ingress rating to IP68, standard DIN range of 0-10 bar and over pressure limit of 15 bar, output signal of 4-20mA for connecting to water pipes with cylindrical pipe threads in accordance with DIN/ISO 228.
The DMK457 Water Pressure Transmitter is a robust and reliable sensor designed for use in harsh industrial environments. Its IP68 ingress protection rating ensures complete protection against dust and prolonged immersion in water, making it suitable for a wide range of applications where moisture and contaminants are a concern. This high level of protection makes the DMK457 ideal for use in applications such as wastewater treatment, flood monitoring systems, and tank level measurement, where the transmitter might be temporarily submerged.
This water pressure transmitter features a standard DIN measuring range of 0-10 bar, covering a broad spectrum of water pressure monitoring needs. The 15 bar overpressure limit provides an additional safety margin, protecting the sensor from damage in case of unexpected pressure spikes. This is particularly important in applications with fluctuating water pressures, such as those found in industrial pumping systems or water distribution networks.
The DMK457 utilizes a 4-20mA output signal, a widely accepted industry standard for transmitting analog sensor data. This signal type offers high noise immunity, making it suitable for long cable runs often encountered in industrial settings. The 4-20mA output is compatible with a wide range of industrial controllers, data acquisition systems, and display devices, simplifying integration into existing infrastructure.
For convenient and secure installation, the DMK457 is equipped with cylindrical pipe threads conforming to DIN/ISO 228. This ensures compatibility with commonly used fittings and facilitates straightforward mounting in various plumbing configurations. The standardized threading also contributes to a reliable seal, minimizing the risk of leaks.
