Keller Series 35X HTC high-temperature pressure transmitter

Monday, 21 November, 2011 | Supplied by: Bestech Australia Pty Ltd


The Series 35X HTC high-temperature pressure transmitter from Keller is primarily designed for biotechnology and food industry applications. The pressure of hot media applied to the diaphragm is transferred via an exposed oil-filled spiral capillary to the sensing element. Heat to a maximum of 300°C is therefore safely dissipated to the atmosphere before it reaches the sensing element when the sensor is optimally mounted.

The 35X HTC is based on the existing Series 30 digitally compensated pressure transmitter range. The 35X HTC is available in ranges from -1 to 3 to 0 to 1000 bar. While the linearity (BSl) is 0.05%FS, the combined error is 0.5%FS for the entire operating temperature band from 20 to 300°C. The frequency response is 100 Hz. Both analog and digital output signals are standard, including RS485, 0-10 V and 4-20 mA. It is possible to use both digital and analog signals concurrently. Supply voltage is 8-28 VDC for the RS485 and 4-20 mA outputs. The 0-10 V signal requires 12-30 VDC input.

Several choices of interface cables are available within the Keller product range to communicate between the 35X HTC and a PC. PROG30 PC-compatible software is available to set up and calibrate the Series 35X HTC, to rescale it from 100% down to 30% FS, to adjust the zero, change the measurement unit and enable several other functions. READ30 data acquisition software is also available to facilitate various graphical presentations, as well as to monitor up to 16 transmitters on the one serial connection.
