High-temperature pressure transmitters - Import export

The ultra-fast M8coolHB pressure transmitter can process pressure changes with a bandwidth of 50 kHz. This is achieved by means of the continuous analog signal that is adjusted by a digital circuit in real time and is amplified to a standardised 0...10V signal. The miniature sensor head with a fine M8 thread can withstand temperatures of up to 1000 °C with suitable cooling, is overload-proof up to a magnitude of five times the measuring range, and is also resistant to vibrations.

The ultra-fast M5HB pressure transmitter can process pressure changes with a bandwidth of 50 kHz. This is achieved by means of the continuous analog signal that is adjusted by a digital circuit in real time and is amplified to a standardised 0...10V signal. The miniature sensor head with a fine M5 thread can withstand temperatures of up to 180 °C, is overload-proof up to a magnitude of five times the measuring range, and is also resistant to vibrations.

The high-temperature pressure transmitters of the 35XHTC series can be used at media temperatures of up to 300 °C. The remote electronics are designed for temperatures of up to 120 °C. They use digital compensation with a mathematical model to achieve an accuracy of 0,5 %FS – in the temperature range from 10 to 40 °C, this value even corresponds to the total error band. In addition to the digital RS485 interface, the X-line transmitters have a rangeable, analog current or voltage output. The standard model of the 35XHTC series has a G1/2 thread as pressure connection.

The high-pressure transmitters of the 7LHPC series use the chip-in-oil technology developed by KELLER, uniting a pressure measuring cell, digital temperature compensation and signal processing in a compact housing made of stainless steel or Inconel. The transmitters are extremely resistant to environmental influences and deliver compensated measurement results as an analog, ratiometric 0,5...4,5V output signal over a wide temperature range.

The pressure transmitters of the 6LHPD series for high pressure applications use the chip-in-oil technology developed by KELLER, uniting a pressure measuring cell, digital temperature compensation and signal processing in a compact housing made of stainless steel or Inconel. The transmitters are extremely resistant to environmental influences and delivery highly accurate measurement results as a digital output signal. The I2C interface and the low supply voltages make it easy to integrate in microcontroller-based systems. The extremely low power consumption is ideal for battery-operated devices. The D line is perfect for IoT solutions.

The series 21DC RFID combines the digital and extremely robust D-line pressure transmitters and data logger electronics with an RFID interface. The built-in battery has a lifespan of 5 to 10 years. The pressure and temperature values are each saved as a pair of numbers in the memory. Instantaneous values and saved data can still be read if the battery is flat, because power is supplied by the reader.

The Series VTP Multi Range Air Velocity Transmitter can simultaneously display and output Air Velocity, Temperature and Pressure (optional). This is the first product to combine all 3 variables in one transmitter making the VTP an exceptional option for multi-variable measuring. The VTP utilizes an industrial 316 Stainless Steel armored RTD sensor as the thermal air velocity measuring component. Using a fully protected 316 SS sensor drastically extends the life of the air velocity sensor and also makes it insensitive to water, dust or corrosion. The VTP comes standard with a LCD and can simultaneously display air velocity, temperature, and pressure. The VTP is easily configured or adjusted in the field with the digital display and keypad. The Air Velocity Range and Pressure Range are both field adjustable as well as units of measure. Other adjustable parameters include signal dampening and low velocity cut off point.
