• Vacuum/compound ranges: -1…+1 to -1…+10 bar
• Output signals: 4…20 mA (2-wire), 0…5 Vdc, 0…10 Vdc, 1…5 Vdc, 1…10 Vdc, 0.1…5.1 Vdc, 0.1…10.1 Vdc
• Accuracy: ±0.25% FSO or ±0.5% FSO (by class)
• Response time: < 1 ms
• Process temperature: -40…+105 °C
• Temperature compensation: -10…+85 °C
• Ingress protection: IP65 / IP67 (depends on electrical connection and correct connector installation)
• Wetted parts: AISI 430F and 17-4 PH

Connections and Options

Standard process connections: G 1/4 DIN 3852-A, 7/16-20 UNF SAE 4, G 1/2 DIN 16288. Optional: G 1/4 female, NPT, M14x1.5, M12x1.5, SAE J1926-2. Electrical connections: DIN43650, M12x1, shielded cable, 6-pole and 7-pole connectors.

Applications

Used in hydraulic power packs, pumps, compressors, presses, test benches, chiller systems, and machinery requiring analog pressure measurement to PLCs, PID controllers, or local indicators.

Output Selection

4…20 mA output is recommended for long cable runs or environments with electromagnetic interference. Voltage outputs are suitable for short-distance connections to analog controller inputs. The TK is a measurement device only; no actuator options are available.

Standards and Compliance

TK conforms to RoHS 2011/65/EU and EMC 2014/30/EU.

FAQ

When to select TK vs. TKDA?
Choose TK when digital Autozero/Span is not required. TKDA provides digital Autozero functionality.

Compatible media?
Fluids compatible with AISI 430F and 17-4 PH, such as hydraulic oil, air, and technical gases.
