On this page your find the information of the electronic devices , we have in our Program. Do you need support , have any questions of remarks , simple contact us .
Which safety pressure relief valve was started to open of leaking first . One of the most difficult question to answer fora refrigeration engineer.
Please look at this detection sensor : the STG . a direct leak will direct detected. no more change or renew of all pressure reliëf valves
A very interesting feature of one relation in our network. A detection sensor just behind the safety pressure relief valve can help to localize the smallest leakage to the safe area line – indicate which safety pressure relief valve was operated.
Safe time by investigation – direct area localisation – visualization local en in your central alarm system.
THE STG sensor – the detection behind your pressure relief valve.
Location for mounting : direct behind the pressure safety relief valve in the line to safe area.

Linear Postion indicators ( LPI) of part load sensors are today used in almost ever screw compressor. The devices can be calibrated to a working distance, where the min position will be indicated with 4 mA and the max distance position with 20 mA .
By auto Vi compressors a linear Position Indicator can also be used to indicate the Vi.
We support costumers with questions as supply linear position indicator for a wide range , even not only in refrigeration industry
The linear position indicators are useful in many situations , even in EX area’s
The complete range from the Howden WRV and XRV models is available
The complete line for Sabroe compressor is available ,incl the older types with a tuning device for old types of SAB 128 and SAB 163
For Gram Compressors there still linear Postion indicators available
Stall was one of the first compressor manufactures , which use the linear Postion indicators . Even today still available .
The complete range from the GEA compressor are available
The complete line for Frick compressor is available.
For SRMtec Compressors there still linear Postion indicators available
also the new line of CSI compressor will be suited with linear postion indicators
To have indicaton of the level of many different devices can be used – We offer several types, which have proven itself over the years
he HB L-t wire sensor is a very compact design. The only height for installation is 115 mm , due to split sensor design. The wire is teflon coated , therefore no risk on faulty alarm by contact with piping. suitable for marine applications.
A successful solution for level indication is the HBT the wired sensor , this sensor is easy to install and is suited with a separate electronically head and measurement sensor.
HBLT-wire is a capacitieve sensor for level measurement of NH3 refrigerant in industrial refrigeration systems.
The sensor has an output signal of 4-20 mA, which is proportional with 0 and 100%. Its output signal is 4 mA for an empty tank and 20 mA for a full tank.
It can be used as a level sensor, or it can be used as a combined level sensor and direct P-regulator of modulating valves e.g. level regulation in a chiller or plate heat exchanger
Adjusting to your situation:
HBLT-wire can be adjusted in length to the current application.
The sensor element consists of a 2mm steel wire as well as a Teflon tube.
Both parts are provided with a length of 4m and can be shortened with diagonal cutters or other pliers.
In cases where the customer wanted to configure the sensor, the target of a maximum of 5 minutes was achieved. There are only two parameters to set up in order to use the sensor for level measurement, which is a process that can easily be carried out in less than 5 minutes
n the refrigeration industry this liquid level indicator is well-know his previous name was AKS41. Basic he is one on the most flexibel liquid level sensor, I personally worked with . In the refrigeration industry were we have liquids , which can easy transfer into gas and create a turbulent liquid bath this sensor is complete adjustable to your situation . Even for the refrigeration industry are the most common refrigerants pre-programmed .
Adjustable are the media, min/ max level and signal damping from 1- 120 seconds.
The sensor is designed as split sensor. powered by 24 VDC and out 4-20 mA.
There are two versions available : with local led indication bar and without.
