We are pleased to show you the new selection of the 2025 latest products created by our partner Kobold Instruments, a company specialized in monitoring, measuring and regulating flows through pressure, level and temperature instruments:

PSD – Electronic Pressure Transmitter

The electronic Kobold pressure transmitter and switch PSD with integrated display is used for continuous pressure measurement and monitoring and allows simple switching point programming without pressurisation. For each switching point, the contact function (NC contact/ NO contact), the reset points and the switching function (hysteresis/window function) can be programmed.

Technical Features:
Measuring range: -1 … +1,5 bar … 0 … +600 bar
Accuracy: ± 0,5% of FS
tmax: +85°C (Medium)
Connection: G ¼
Material:
Connection of st.steel 1.4542
Housing of steel/die cast metal galvanised
Output:
1 analogue output 4-20 mA or 0-10 V (switchable)
2 switching output PNP
Options:
rotatable and invertible display; rotatable electrical connection;
switch point status indication via LEDs

VKP – Viscosity Compensated Flow Meter – Switch (Plastic)

The Kobold plastic flowmeters model VKP operate on a special suspended float principle with cylindrical measuring tube and spring-loaded float with orifice.
The float in model VKP-3 has slots moulded on the outside, which protect the instrument from soiling by depositing dirt particles.

Technical Features:
Measuring / switching range:
2 – 20 … 20 – 100 l/min water
1 – 18 … 10 – 75 l/min oil
Connection: G 1, 1″ NPT male thread, solded pipe, connection parts G ½, G ¾
Material: polysulfone, stainless steel 1.4310
pmax: 16 bar
tmax: 120°C
Accuracy: ±5 % of full scale
Option: reed contact

VKM – Viscosity Compensated Flow Meter – Switch (Metal)

The Kobold flowmeters and switches model VKM have a spring-loaded float, which slides within a cylindrical measuring tube and has an integral orifice which is believed to be unique. This and other design features means that it has for the first time become possible to create a flowmeter and switch which fully compensates for viscosity and to a large extent for density even with very low flows.

Technical Features:
Measuring / switching range:
0.01 – 0.07 … 8 – 80 l/min liquid
1 – 540 mm²/s viscosity
Connection: G ¼ …1, ¼ …1″ NPT female thread
Material: brass, stainless steel
pmax: 250 (brass), 350 bar (stainless steel)
tmax: 100°C
Output: max. 2x contact, 1x analogue
Power supply: 24 VAC/DC , 24 VDC ±20 %, max. 250 VAC
Electrical connection: plug DIN EN 175301-803, cable
Accuracy: ±4 % of full scale
Option: block valve BVB
Option (VKM with ADI): analogue output, counter, digital display, relays, panel mounting, block valve BVB
Approval: cCSAus, ATEX, IECEx

NBK – Bypass Level Indicator ATEX

Kobold bypass level indicators are used for continuous measurement, display and monitoring of liquid levels. The bypass tube is attached onto the side wall of the vessel. According to the law of communicating tubes the level in the bypass tube equals the level in the vessel. A float with embedded circular magnets in the bypass tube follows the liquid level and transfers it in a non-contacting manner to a display fitted outside the tube or to a monitoring device.

Technical Features:
Measuring length: max. 5.5 m (if longer: 2 parts)
Connection: DIN-flange DN15 … DN50, ASME-flange ½” … 1¼”
Material: stainless steel 1.4571
pmax: PN100
tmax: 400°C
Accuracy transducer: ±1 mm
Option: transmitter 4 – 20 mA, contacts
Certificates: ATEX

MAN-V – Pressure Gauge with Built-In Pressure Transmitter

The Kobold all stainless steel pressure transducers are suitable for harsh conditions resulting from high demands on pressure measurement in production plants of the chemical or other comparable industries.
The use of high quality stainless steel for both measuring system and housing guarantees resistance against aggressive media and environment.

Technical Features:
Measuring range: -1 … 0 bar … 0 … +600 bar
Connection: G ½, 1/2″ NPT male thread, stainless steel
Housing material: stainless steel
Housing: Ø 100 mm
Accuracy: ≤0.5% FS
Analogue output
Option: filling liquid

Kobold NUS – Ultrasonic Level Meter

The Kobold ultrasonic level meter, model NUS, is used for non-contact, continuous level and volume measurement in vessels or for flow measurement in open channels. Level measurement technology based on the non-contacting ultrasonic principle is especially suited for applications where, for any reason, no physical contact can be established to the surface of the material to be measured.

Technical Features:
Measuring range: liquids up to 25 m, solids up to 10 m
Connection: G 1½ , G2, 1½” NPT, 2″ NPT male thread,
flange DN80, 125, 150, ANSI 3″,5″,6″
Material connection: PP, PVDF
pmax: 3 bar abs.
tmax: 90°C
Accuracy: ±0.2 % of reading ±0.05 % of full scale
Power supply: 12 – 36 VDC, 2-wire
Output: 4 – 20 mA, relay
LCD-indication and programming unit
