Industrial Devices

immersible DEVICE DPg-4М  And MAIN DEVICE DM-5М

ДПг-4М и ДМ-5М

 



 

Experience, quality, reliability 

Immersible and main armature (device) are designed to install measurement and auxiliary electrodes in pipelines or control system capacities and capacities of automatic рН control of operational processes and to connect electrodes with converters. The built-in Automatic Temperature Compensator improves measurement accuracy in environments with varying temperature.

Advantages of device 
 

v   Wide range of standard sizes.

v   Use of chemically resistant materials.

v   The built-in Automatic Temperature Compensator improves measurement accuracy in environments with varying temperature.

                                                     * Case is made of steel 12Х18Н10Т and titanium ВТ1-0.

** Armature is completed according to customer's request for additional fee with measuring glass electrode type ESP-01-14, ESP-04-14 and auxiliary electrodes type EHSV-1 (saturated, external) with electrolytic key or static electrodes EVP-08. Contact of electrodes EHSV-1 with measuring medium created by the expiration of saturated KCL solution through the mica separators of electrolytic key. Potential respectively normal hydrogen electrode at 20 ° C is equal to (201 ± 3) mV.

Pressure of measuring medium should not exceed 0.6 MPa. When the pressure fluctuation is over ± 0,02 MPa the pressure regulator of tracking action RDS-1 must be used, which is available upon request.

When ordering, specify the symbol of armature with the required length of immersible part (in case of delivery of the electrodes - the symbol of the measuring electrode, the code of isopotential point coordinates) and TU number. For example: Armature DPg-4M-8-ESP-04-14.7 - TU RB 05796587.009-99.
