Description
Specifically designed for measuring wastewater levels, typically conducted in aggressive environments, the 36KyX series transmitter features:
- use of a wide sensitive membrane;
- compact overall dimensions.
The 36KyX includes a monolithic diaphragm made of Kynar®, which combines Teflon's resistance to aggressive environments with excellent strength and wear resistance.
This, in turn, simplifies the installation of the transmitter and eliminates the need for bulky and expensive protective structures.
The 36KyX series transmitter uses reliable, time-tested piezoresistive technology combined with a modern KELLER chip design. It also employs a microprocessor-based signal conditioning and temperature compensation circuit, providing excellent accuracy and repeatability over a wide temperature range.
The 36KyX is ideal for pump control systems that require a standard 2-wire (4...20 mA current loop) or 3-wire (0...10 V) sensor output signal.
The RS485 interface allows users to configure the analog output to any desired limit within the standard pressure range. The 36KyX is typically suspended in the liquid using a standard cable with a capillary tube made of Hytrel® material.
Optional: lightning strike protection makes this transmitter perfectly suitable for installation in areas prone to regular damage caused by transient processes induced by lightning.
Using KELLER CCS30 software along with the appropriate cable and adapter allows the user to configure the 36KyX analog output. It is also possible to change the display and recording method for pressure and temperature. Access to other useful functions is also available. All available functions are defined in the Series 30 sensor data transmission protocol. The CCS30 program and the Series 30 sensor protocol description are freely available on the company website.
