MEASUREMENT & MONITORING A CLASS LEADING TRANSMITTER
KOBOLD
New pressure instrument release from Kobold
Kobold have released the latest version of their electronic digital pressure gauge ; model MAN-SC for battery powered , and model MAN-LC for 24Vdc power with IO-link .
Outwardly , the two versions are similar in appearance and share most of the screen functionality features which are now accessed via capacitive Touchpads , however , depending on the application and use , each instrument version may be defined differently . For example , the battery powered instrument defined as a Digital Pressure Gauge , while the 24Vdc version can be defined as a Digital Pressure Transmitter , which considering the innovative features of each version is rather simplistic , but it goes some way to define the natural application areas of the two versions .
Kobold ’ s previous Digital Pressure Gauge , the MAN-SD , remained in production for 23 years , proving a very robust and popular instrument . With that record of robustness and reliability in mind , Kobold carefully developed the new MAN-SC / LC instruments , prioritising these core values , but also incorporating the wishes of customers worldwide to produce a high-quality digital pressure gauge which satisfies traditional user applications , but also reaches out to new industry sectors .
A key target requirement in Kobold ’ s design brief was not to exceed the retail price of the previous model , which for a new innovative electronic instrument product manufactured in Germany was not an easy task for Kobold ’ s production engineers , however , the retail price remains the same , and we think this offers considerable value for money in the current global marketplace .
SO WHAT ’ S NEW ?
• The new alpha-numeric 14-segment reflective LC‐display screen is impressive , with a full 5-digit display , and digit height of 16mm .
• The electronic screen module can now be rotated in 90 ° increments ; ideal for side mounted or inverted installations .
• The gauge head position can now be radially adjusted after installation for perfect positioning .
• Access to the screen options is now by capacitive Touchpads .
• An impressive range of measuring units are now accessible for selection from the programming menu , for example ; kPa , MPa , bar , mbar , psi , kN , N , torr , inWC , mmWC , inHg , USR ( user-defined measuring unit ), providing more options than any comparative instrument so far .
• Peak memory is featured , as is password protection , and reset to factory setting .
• Battery life with 9V Lithium is now increased to 22,500 hours ( 2.5 years ).
• A zero ( tare ) function is now more easily accessible from within the menu , ideal for calibration .
By popular request , a rubber protective case cover is now available as an option , ideal for test engineers and vulnerable areas of installation . Measuring ranges are now available from -1 … 0 ...+ 1600 Bar , which is impressive .
The range of process connection threads has also been substantially increased and now include metric threads . Additionally , from the options list Kobold are able to assemble diaphragm and hygienic process connections .
Another unique application feature , only available from Kobold , is calculation of Force Value which is included in the programming menu . This is calculated from the measured pressure value and a programmable reference area . There are many industrial applications that will benifit from this feature but the most common request came from the construction test and safety sector for a digital pressure gauge to be included as part of the test equipment for compliance to DIN EN 1090 , for example , testing of anchors and fastenings in masonry and concrete to provide conformity assessments and certification in accordance with DIN EN 1090 .
SO WHY PRODUCE A DIGITAL PRESSURE GAUGE WITH AN INTEGRAL TRANSMITTER ? The MAN-LC provides so much more than the traditional barrel style digital pressure transmitter such as Kobold ’ s popular PSD instrument , which followed the industry design trend for compact digital instruments . The most beneficial features of the MAN-LC are the clarity of the large digital display , and the multiple programmable features of the instrument .
SO WHAT ’ S NEW ?
• The new MAN-LC model comes with IO-Link , the only
Digital Pressure Gauge worldwide with IO-Link .
• Many of the standard features included in the battery powered MAN-SC model are typical , however , the MAN-LC is 24Vdc powered and therefore further features are included , most noticeable when viewing the LC-display , is a backlit screen which combined with the new large display characters provides a clarity which traditional digital barrel transmitters cannot provide .
• Analogue and frequency , plus alarm outputs are standard , and an optional pluggable relay module with 2x potentialfree SPDT contacts is available either factory assembled , or as a retrofit kit . This enables a customer to specify a very powerful pressure instrument specification .
• Added to these features , the addition of a variety of flanged and diaphragm seal process connections extends the application reach to many industrial applications .
Kobold believe they have answered the most requested technical wishes from their customers worldwide , and in doing so , have produced a class leading digital pressure gauge / transmitter , in line with future Industry 4.0 requirements . Kobold has International sales offices and distributors who will be happy to offer support .
