Comments Off on BT6-B Balanced Pressure Thermostatic Trap for Clean Steam
Is your clean steam process getting to the temperature you require? If not, you may be experiencing condensate back-up or air binding.
If this is the case, it would be prudent to ensure that the steam trap is suitable for the application. Though clean steam thermodynamic steam traps are suitable for drip applications, a balanced pressure thermostatic trap, constructed of 316L, should be used for process applications. The balanced pressure thermodynamic steam trap should contain a minimum sub cooled element, be installed to allow for full drainage, contain an un-insulated drip leg of no less than 12″* and be fully open when cold. In the unlikely event that these can’t be met, traps can be provided with a fixed bleed.
*Please note that the length of the drip leg may be able to be adjusted depending on the load. The length of the drip leg in light load applications may be shortened, provided that appropriate calculations are made.
Comments Off on Hawk Centurion Guided Radar (CGR) has success with Oil/Water Interface
HAWK was recently invited to “put up and show” how our guided wave radar (GCR) could work in a real world environment for Oil & Water interface. An Oil & Gas Services company located in USA needed accurate measurement of oil level and accurate measurement of the salt water interface in a series of tanks to efficiently separate salt water from oil.
This customer has experienced quality problems and accuracy problems with other manufacturers of Guided Radar devices and they asked us to help. The problems experienced included inaccurate level readings, high level alarms, signal dropping out, slow response times and constant lack of support.
In addition, this customer was looking for MODBUS communication since this is how they setup their control scheme for the entire Horizontal Pumping Systems (HPS).
The challenge was for HAWK to prove our Centurion Guided Radar (GSR) system for level and interface measurement. In addition, HAWK had to develop a MODBUS version of the CGR since the only option was 2-Wire HART 7 version.
HAWK was able to install a CGR 2-Wire Hart device within 2 weeks to prove the ease of set-up and commissioning and a finished CGR MODBUS version within 6 weeks of the request. Oil level and Salt Water Level accuracy compared with hand dips done over a 3 day period with very good results and the customer’s reaction was “WOW”.
These units have been installed with no special setup or adjustments needed…just the standard HAWK settings. The CGR installation had the same mounting as the competitors and the same conditions.
This customer has now ordered more than 40 CGR’s and HAWK has become the standard level/interface device!

Comments Off on Transmitter for gas density, temperature, pressure and humidity of SF6 gas
The model GDHT-20 transmitter is a multi-sensor system with digital output for the measurement parameters of pressure, temperature and humidity. Based on these measured values, the condition-related data can be determined.
In order to prevent system failures in switchgear and, with that, network outages, the permanent monitoring of the gas density and moisture content is essential.
The GDHT-20 transmitter calculates the current gas density from the pressure and temperature using a complex virial equation in the transmitter’s powerful microprocessor. Pressure changes resulting from thermal effects will be compensated by this and will not affect the output value.
In addition, the GDHT-20 transmitter delivers humidity or dew point information online, which enables monitoring within the terms of Cigre guidelines and IEC Standards.
Due to its high long-term stability, the transmitter is maintenance-free and requires no recalibration. Through the hermetically sealed weld seam and a measuring cell design without sealing elements, the permanent sealing of the measuring cell is ensured.
The EMC characteristics fulfill the IEC 61000-4-2 through to IEC 61000-4-6 standards and guarantee an interference-free data output.
Permanent monitoring of the relevant gas condition parameters in closed tanks
For indoor and outdoor SF6 gas-insulated equipment
High-accuracy sensor technology
MODBUS® output protocol via RS0485 interface
Ingress protection IP65
Very good long-term stability and EMC characteristics
